Climate Change

The world is warming up, with 2023 being by far the hottest year since record keeping began and 2024 shaping up to be hotter yet. But these changes only involve one or two degrees. What's the big deal?

The amount of energy required to raise the temperature of one liter of water by one degree is one kilocalorie (kcal). Scaling up, the amount of energy required for a one-degree increase in the water temperature of the Gulf of Mexico is 2,434,000,000,000,000,000 kcals. That's 25 million times more energy than released by the WW-II atomic bomb that destroyed the city of Hiroshima and killed more than 100,000 people.

So, for every one degree increase in water temperature, the Gulf of Mexico takes on 25-million atomic bombs worth of new energy, which is then available to fuel hurricanes and other storms. Maybe a one-degree rise in temperature is a big deal.

Climate change and the cost-of-living squeeze in desert lizards.

Science (New York, N.Y.), 387(6731):303-309.

Climate warming can induce a cost-of-living "squeeze" in ectotherms by increasing energetic expenditures while reducing foraging gains. We used biophysical models (validated by 2685 field observations) to test this hypothesis for 10 ecologically diverse lizards in African and Australian deserts. Historical warming (1950-2020) has been more intense in Africa than in Australia, translating to an energetic squeeze for African diurnal species. Although no net impact on Australian diurnal species was observed, warming generated an energetic "relief" (by increasing foraging time) for nocturnal species. Future warming impacts will be more severe in Africa than in Australia, requiring increased rates of food intake (+10% per hour active for diurnal species). The effects of climate warming on desert lizard energy budgets will thus be species-specific but potentially predictable.

Rethinking Conservation and Restoration Strategies of Endangered and Key Medicinal Clavicarpa Plants in Yunnan-Kweichow Plateau's Karst Areas Under Climate Change.

Ecology and evolution, 15(1):e70790.

The Clavicarpa species, valued for their pharmaceutical, ornamental, and economic importance, exhibit notable rarity and endemism in the Karst areas of the Yunnan-Kweichow Plateau in China. These species face significant threats from habitat loss and fragmentation, leading to a decline in biodiversity. To mitigate these threats, the Maxent algorithm was employed to analyze current and future distribution patterns, with a particular focus on the influence of climate variables in predicting potential distribution shifts and assessing extinction risks under the optimistic SSP1-2.6 and the pessimistic SSP5-8.5 socioeconomic scenarios. The EC-Earth3-Veg, MRI-ESM2-0, and MPI-ESM1-2-HR models were utilized for conservation status assessment and project future distributions for four time periods: the present, 2030s, 2050s, and 2070s. The minimum temperature during the coldest month (Bio 6) was identified as the most critical environmental factor, influencing both habitat contraction and expansion. Our modeling indicates that regions such as South, Central, and East China, particularly areas east of the Aihui-Tengchong line and south of the Yangtze River, exhibit the highest suitability for Clavicarpa species within the geographical coordinates of 18° N-45° N and 97° E-120° E. Conversely, climate change projections suggest a habitat expansion for Impatiens claviger, Impatiens tubulosa, Impatiens pritzelii, and Impatiens apalophylla, while Impatiens guizhouensis and Impatiens wilsonii face increased extinction risks. Specifically, I. claviger, I. tubulosa, and I. apalophylla are expected to shift northward, necessitating potential relocation to southern regions, while I. guizhouensis and I. wilsonii are projected to experience habitat losses of over 23.94% and 9.13%, respectively. Our research provides a robust scientific foundation for the conservation and sustainable utilization of these important pharmaceutical species and offers a framework for effective biodiversity management. We recommend using protected areas as a basis for the future conservation, breeding, cultivation, and utilization of Clavicarpa species.

Climate change and epigenetics: Unraveling the role of methylation in response to thermal instability in the Antarctic plant Colobanthus quitensis.

Physiologia plantarum, 177(1):e70043.

Low temperatures are one of the critical conditions affecting the performance and distribution of plants. Exposure to cooling results in the reprogramming of gene expression, which in turn would be mediated by epigenetic regulation. Antarctica is known as one of the most severe ecosystems, but several climate models predict an increase in average temperature, which may positively impact the development of Antarctic plants; however, under warmer temperatures, plants' vulnerability to damages from low-temperature events increases. Here, we evaluated the impact of these events on the acclimation process, with a focus on how methylation influences the induction of cold response genes. According to the results, an increase in the number of methylations in the promoter regions is associated with lower expression of these genes. Similarly, in populations where this relationship is observed, individuals acclimated to the projected climate change condition are more vulnerable, as their average temperature is lower in the face of a cold event compared to individuals acclimated to the current antarctic condition. This research is the first report highlighting the role of methylation in response to cold and its influence on the transcriptional responses of the antarctic plant Colobanthus quitensis facing climate change projections.

Discovery of Laacher See eruption in speleothem record synchronizes Greenland and central European Late Glacial climate change.

Science advances, 11(3):eadt4057.

To assess the impact of ongoing, historically unprecedented Arctic ice melting, precisely synchronized chronologies are indispensable for past analogs of abrupt climate change. Around 12,900 years before present (B.P.), the Atlantic-European realm experienced an abrupt relapse to near-glacial climate conditions attributed to Arctic meltwater fluxes, the Younger Dryas. However, it remained unclear how fast this climatic change propagated southward into Europe as terrestrial and ice-core chronologies are not sufficiently synchronized. Here, we use a volcanic sulfur spike identified in a speleothem from Germany to link the Laacher See eruption (LSE), a key chronostratigraphic marker in European terrestrial archives, to a previously unidentified sulfate spike in the Greenland ice-core record. The LSE, dated to 13,008 ± 8 years B.P.1950, thus synchronizes radiometric and ice-core calendars back in time, which consistently demonstrates that the LSE predates the onset of the Younger Dryas cooling by about 150 years, both in Greenland and Europe.

What drives farmers' behavior under climate change? Decoding risk awareness, perceived impacts, and adaptive capacity in northern Italy.

Heliyon, 11(1):e41328.

Understanding climate change in a precise and timely manner may assist in gauging the occurrence and seriousness of its impacts, thereby boosting the adaptive capacity and responsiveness of farmers. This investigation looks into farmers' knowledge of climate change, their perception of risks and impacts, and the strategies they anticipate to tackle the challenges of adaptation. A well-structured online survey covering risk awareness, perception, and adaptation was used to randomly sample 460 respondents from 12 irrigation districts in northern Italy. Descriptive and multivariate statistics, including structural equation modeling, were employed to outline the profiles of farmers, explore the drivers shaping their behavior, and disentangle the magnitude and direction underpinning their adaptive capacity. Findings revealed that farmers recognize changes in climate and perceive its variability and effects, such as rising temperatures, extreme heat events, and irregular precipitation. Farmers blend adaptive measures, including climate services and insurance, with preventive mechanisms like reducing fertilizer use, rotating and diversifying crops, and introducing soil conservation techniques. However, they encounter obstacles such as poor government assistance, expensive investments and overlay intricate regulations. Regarding decision-making processes, the structural model demonstrated that 1) recognizing climate change can sensibly predict alterations in farmers' behavior concerning climate impacts while 2) there is a lack of correlation between perceiving risks and implementing risk adaptation measures. Interestingly, factors such as farming experience, farm size, area under irrigation, and primary crop type significantly influence how risks are perceived and what measures are adopted. In light of these results, we offer guidance for upcoming research.

Climate change impacts flowering phenology in Gongga Mountains, Southwest China.

Plant diversity, 46(6):774-782.

Flowering phenology of plants, which is important for reproductive growth, has been shown to be influenced by climate change. Understanding how flowering phenology responds to climate change and exploring the variation of this response across plant groups can help predict structural and functional changes in plant communities in response to ongoing climate change. Here, we used long-term collections of 33 flowering plant species from the Gongga Mountains (Mt. Gongga hereafter), a biodiversity hotspot, to investigate how plant flowering phenology changed over the past 70 years in response to climate change. We found that mean flowering times in Mt. Gongga were delayed in all vegetation types and elevations over the last 70 years. Furthermore, flowering time was delayed more in lowlands than at high elevations. Interestingly, we observed that spring-flowering plants show earlier flowering times whereas summer/autumn plants show delayed flowering times. Non-synchronous flowering phenology across species was mainly driven by changes in temperature and precipitation. We also found that the flowering phenology of 78.8% plant species was delayed in response to warming temperatures. Our findings also indicate that the magnitude and direction of variation in plant flowering times vary significantly among species along elevation gradients. Shifts in flowering time might cause trophic mismatches with co-occurring and related species, affecting both forest ecosystem structure and function.

Development of an agenda for research and action on climate change and health in the Caribbean.

Revista panamericana de salud publica = Pan American journal of public health, 49:e4.

This paper delineates the development of the Caribbean Research for Action Agenda which aims to empower Caribbean Small Island Developing States to reduce their vulnerabilities to the effects of climate change on health. The Caribbean Research for Action Agenda emerged from collaboration between nongovernmental organizations, academic institutions, and multilateral agencies that organized a conference on climate change and health in the Caribbean. This Agenda was formulated by prioritizing research areas, synthesizing evidence from conference presentations and scientific literature, and holding consultations with stakeholders and experts. The Agenda provides information on 18 priority areas for research and action categorized into four domains: climate change health impacts, exposures, and vulnerability; adaptation, planning, and resilience for health; mitigation actions and health co-benefits; and resources and engagement for climate change and health action. Cross-cutting findings underscore the need for: greater public and professional awareness; a more climate-literate health workforce; interdisciplinary collaboration to address institutional silos; attention to social and economic mediating factors; equitable interventions for vulnerable groups; and enhanced monitoring and surveillance of climate-sensitive health outcomes. The Caribbean Research for Action Agenda is a foundational tool to inform research, guide multisectoral collaboration and capacity-building, develop evidence-based policy, and inspire community action-based advocacy related to climate change and health.

A systematic review on the trend of transcriptomic study in livestock: An effort to unwind the complexity of adaptation in a climate change environment.

Heliyon, 11(1):e41090.

Heat stress has been proven to cause negative effects on livestock leading to lower productivity and economic value. Understanding how heat stress manifests within an animal's body is the first step in devising a heat stress mitigation strategy; transcriptomic studies are one of the methods used. Here, using a systematic literature review methodology, we examine the recent decade of transcriptomics' application to the study of livestock adaptation. We identified 152 studies that met our criteria for using transcriptome methods to heat stress adaptation and were published within the last ten years. Our analysis demonstrates the growing popularity and application of transcriptome approaches in the investigation of the response of ruminants, pigs, and poultry livestock to heat stress. Majority of the works was done in chicken and cattle using multiple organs as the sample, with qRT-PCR as the most employed technique. It has been established that a variety of biomarkers can be used to assess animals under heat stress, such as the HSPs, ILs, and TLRs. Although transcriptomics has lately been employed extensively to uncover the mechanism of heat adaptation, this adaptive feature's complex mechanism remains unclear, leaving many knowledge gaps for investigation. A more complex studies involving more various cell types, organs, or even model organisms using multi-omics approach could be the future research direction in understanding the heat stress effects on livestock better.

The potential impact of climate change on medication access and quality deserves far more attention.

One health (Amsterdam, Netherlands), 20:100957.

Notwithstanding the obvious interconnection between humans and the world that they share with non-human inhabitants, the impact of our changing climate on certain aspects of the public health ecosystem has been under-investigated. We briefly describe some of the possible climate-induced changes in the procurement, distribution, access and use of medications, including those for animals generally and livestock specifically. A fuller understanding of the effect of climate change on medicine supply, access, use and quality, including how these affect antimicrobial resistance, would contribute to the further development of the "One Health" and "One Health Systems" concepts. We suggest that this understanding is not yet available, even though the changing incidence of infectious diseases due to changing climate has been studied. There is a need for improved understanding of the impact of extremes of humidity and heat on medication quality and research into heat-stable medicines as well as strategies for the improving resilience of the pharmaceutical supply and distribution system in complex public health emergencies caused by aberrant weather patterns.

Nonlinear exposure-response associations of daytime, nighttime, and day-night compound heatwaves with mortality amid climate change.

Nature communications, 16(1):635.

Heatwaves are commonly simplified as binary variables in epidemiological studies, limiting the understanding of heatwave-mortality associations. Here we conduct a multi-country study across 28 East Asian cities that employed the Cumulative Excess Heatwave Index (CEHWI), which represents excess heat accumulation during heatwaves, to explore the potentially nonlinear associations of daytime-only, nighttime-only, and day-night compound heatwaves with mortality from 1981 to 2010. Populations exhibited high adaptability to daytime-only and nighttime-only heatwaves, with non-accidental mortality risks increasing only at higher CEHWI levels (75th-90th percentiles). In contrast, compound heatwaves posed a super-linear increase in mortality risks after the 25th percentile of CEHWI. Associations of heatwaves with cardiovascular mortality mirrored those with non-accidental mortality but were more pronounced at higher CEHWI levels, while significant associations with respiratory mortality emerged at low-to-moderate CEHWI levels. These results highlight the necessity of considering the nonlinear health responses to heatwaves of different types in disease burden assessments and heatwave-health warning systems amid climate change.

Impacts of climate change on storm event-based flow regime and channel stability of urban headwater streams.

Journal of environmental management, 374:123994 pii:S0301-4797(24)03981-1 [Epub ahead of print].

Due to the recent improved availability of global and regional climate change (CC) models and associated data, the projected impact of CC on urban stormwater management is well documented. However, most studies are based on simplified design storm analysis and unit-area runoff models; evaluations of the long-term, continuous hydrologic response of extensive stormwater control measures (SCM) implementation under future CC scenarios are limited. Moreover, channel stability in response to CC is seldom evaluated due to the input data required to develop a long-term, continuous sediment transport model. The study objective was to evaluate the impact of CC on storm event-based flow regimes and channel stability in a small, urbanized catchment (0.9 km[2]) in Montgomery County, Maryland, USA. This study employed a previously developed sequential, hierarchical modeling approach, integrating a watershed-scale Storm Water Management Model (SWMM) with the Hydrologic Engineering Center River Analysis System (HEC-RAS) to achieve the study goal. Ensemble modeling results indicate that conclusions related to impacts on SCM performance drawn from simplified, unit area models are not supported by findings from dynamic, continuous simulations that consider the complexities of real urban catchments and SCM interactions. Despite a general decrease in the total rainfall amount of individual storm events for most storm events, there is a noted increase in intensity for nearly all future storm events compared to current climatic conditions. This change in storm event-based rainfall pattern is expected to drive the catchment-scale hydrology to a flashier regime in the future, which in turn is expected to increase the extent of channel erosion compared to the current climate condition. A multicriteria design approach considering the interplay of multiple SCMs and local sediment transport capacity is thus necessary to ensure channel stability under changing climate.

Forecasting Range Shifts in Terrestrial Alpine Insects Under Global Warming.

Ecology and evolution, 15(1):e70810.

Anthropogenic planetary heating is disrupting global alpine systems, but our ability to empirically measure and predict responses in alpine species distributions is impaired by a lack of comprehensive data and technical limitations. We conducted a comprehensive, semi-quantitative review of empirical studies on contemporary range shifts in alpine insects driven by climate heating, drawing attention to methodological issues and potential biotic and abiotic factors influencing variation in responses. We highlight case studies showing how range dynamics may affect standing genetic variation and adaptive potential, and discuss how data integration frameworks can improve forecasts. Although biotic and abiotic factors influence individual species responses, most alpine insects studied so far are shifting to higher elevations. Upslope shifts are often accompanied by range contractions that are expected to diminish species genetic variation and adaptive potential, increasing extinction risk. Endemic species on islands are predicted to be especially vulnerable. Inferences drawn from the responses of alpine insects, also have relevance to species in other montane habitats. Correlative niche modelling is a keystone tool to predict range responses to planetary heating, but its limited ability to consider biological processes underpinning species' responses complicates interpretation. Alpine insects exhibit some potential to respond to rising temperatures via genetic change or phenotypic plasticity. Thus, future efforts should incorporate biological processes by using flexible hybrid niche modelling approaches to enhance the biological realism of predictions. Boosting scientific capability to envisage the future of alpine environments and their associated biota is imperative given that the speed and intensity of heating on high-mountain ecosystems can surpass our ability to collect the empirical data required to guide effective conservation planning and management decisions.

Climate Change and Veterinary Medicine: A Call to Action for a Healthier Planet.

F1000Research, 13:1360.

Climate change is rapidly transforming ecosystems and reshaping the landscapes of animal health, with profound consequences for public health, food security, and biodiversity. Rising temperatures, shifting weather patterns, and increased frequency of natural disasters are driving the emergence and spread of infectious diseases, particularly zoonotic and vector-borne diseases. These environmental shifts endanger the health and welfare of animals and the delicate balance between human populations, livestock, and wildlife. As the stewards of animal health, veterinarians are uniquely positioned to lead the change in addressing these complex challenges at the nexus of human, animal, and environmental health and well-being. This article calls for urgent actions to integrate climate adaptation and mitigation strategies into veterinary practice and education. It underscores the critical need for veterinarians to embrace the One Health approach to tackle climate-driven disease outbreaks and the growing threat of antimicrobial resistance to safeguard human and animal populations while protecting natural ecosystems. The article further explores the role of veterinarians in fostering sustainable agricultural practices, reducing the environmental impact of livestock production, conserving biodiversity and advocating for policy reforms that protect both animal and planetary health. As we face an era of unprecedented climate disruption, this call to action aims to inspire the global veterinary community to actively get involved in combating climate change and its worst impacts. By building climate-resilient practices, enhancing disease surveillance, and championing environmental stewardship, veterinarians can contribute significantly to a healthier, more sustainable future for all species on Earth.

Assessing the distribution pattern of Saussurea medusa under climate change using an optimized MaxEnt model in Qinghai-Xizang Plateau.

Environmental monitoring and assessment, 197(2):165.

Saussurea medusa is a rare alpine plant with significant medicinal value. To better understand the changes in its habitat in the context of climate change, this study used an optimized MaxEnt model to predict the current and future habitat of S. medusa under four shared socioeconomic pathways (SSPs) across three time periods (current, mid-century, and end-century) based on three climate system models. The results showed that the suitable habitat of S. medusa is mainly located in the southern and eastern parts of the Qinghai-Xizang Plateau (QXP), exhibiting a fragmented distribution pattern. The future suitable area of S. medusa is projected to decrease significantly by 42.5% to 96.7%, accompanied by a southward shift in its centroid and an upward shift in altitude. The study found that the highest temperature in the warmest month is the most important environmental factor affecting the distribution of S. medusa. This species is highly sensitive to climate change and requires urgent protection measures. Priority should focus on strengthening habitat protection in the southeastern Qinghai-Xizang Plateau, where some stable habitats remain outside protected areas. Expanding population monitoring, promoting ex-situ conservation, enhancing public education, and encouraging community involvement are essential. Additionally, as a medicinal plant, alternative strategies are needed to curb overharvesting of wild resources.

Heat-tolerant subtropical Porites lutea may be better adapted to future climate change than tropical one in the South China Sea.

The Science of the total environment, 962:178381 pii:S0048-9697(25)00015-4 [Epub ahead of print].

Coral reefs are degrading at an accelerating rate owing to climate change. Understanding the heat stress tolerance of corals is vital for their sustainability. However, this tolerance varies substantially geographically, and information regarding coral responses across latitudes is lacking. In this study, we conducted a high temperature (34 °C) stress experiment on Porites lutea from tropical Xisha Islands (XS) and subtropical Daya Bay (DY) in the South China Sea (SCS). We compared physiological levels, antioxidant activities, and transcriptome sequencing to explore heat tolerance mechanisms and adaptive potential. At 34 °C, both XS and DY corals experienced significant bleaching and the physiological/biochemical index decreased, with XS corals exhibiting greater changes than DY corals. Transcriptome analysis revealed that coral hosts respond to heat stress mainly by boosting metabolic activity. The subtle transcriptional responses of zooxanthellae C15 underscored the host's pivotal role in thermal stress responses. DY coral hosts showed lower bleaching, stronger physiological plasticity, and higher temperature tolerance thresholds than XS, indicating superior heat tolerance. This superiority is linked to negative feedback transcriptional regulation strategies, including active environmental stress response and genetic information damage repair. The differences in thermal adaptability between tropical and subtropical P. lutea in the SCS may be attributed to their genetic differences and native habitat environments, suggesting that subtropical P. lutea may have the potential to adapt to future climate change. This study provides novel insights for predicting the fate of corals at different latitudes in terms of global warming and provides instructive guidance for coral reef ecological restoration.

Global surgery and climate change: how global surgery can prioritise both the health of the planet and its people.

BMC surgery, 25(1):21.

Climate change is an emerging global health crisis, disproportionately affecting low- and middle-income countries (LMICs) where health outcomes are increasingly compromised by environmental stressors such as pollution, natural disasters, and human migration. With a focus on promoting health equity, Global Surgery advocates for expanding access to surgical care and enhancing health outcomes, particularly in resource-limited and disaster-affected areas like LMICs. The healthcare industry-and more specifically, surgical care-significantly contributes to the global carbon footprint, primarily through resource-intensive settings, i.e. operating rooms that generate greenhouse gases and substantial medical waste. Therefore, Global Surgery efforts aimed at improving surgical access through an increase in surgical volumes may inadvertently exacerbate health challenges for vulnerable populations by further contributing to environmental degradation. This predicament is particularly pronounced in LMICs, who already suffer from a disproportionate share of the global burden of disease, and where the demand for surgery is rising without corresponding resilient infrastructure. LMICs face a double jeopardy of health inequity coupled with climate vulnerability. As a movement positioned to improve health around the world, Global Surgery has an increasingly significant role in envisioning and ensuring a sustainable future. Global Surgery initiatives must prioritise sustainable infrastructure in both high-income countries (HICs) and LMICs, all while accounting for the unequal polluting contributions between HICs and LMICs and, consequently, moral responsibilities moving forward. Moreover, through targeting upstream causes of poor health at urban and perioperative levels, Global Surgery's interventions may help to reduce the global burden of disease-avoiding preventable surgeries and their carbon footprints from the outset. Altogether, Global Surgery and climate change are two matters of social justice whose solutions must synergistically centralise the health of both the planet and its most vulnerable people.

Mitigating anthropogenic climate change with aqueous green energy.

Scientific reports, 15(1):1700.

Reaching net zero emissions and limiting global warming to 2 °C requires the widespread introduction of technology-based solutions to draw down existing atmospheric levels and future emissions of CO2. One such approach is direct air CO2 capture and storage (DACCS), a readily available, yet energy-intensive process. The combination of DACCS and ocean thermal energy conversion (OTEC) allows for independently powered carbon capture plants to inject concentrated carbon into deep marine sediments where storage is generally safe and permanent. OTEC is a form of electricity production that exploits the temperature difference between deep and shallow ocean waters, and can power DACCS on floating platforms at a price competitive with coal-generated electricity. Here we highlight the scale of the challenge facing society. We show that a safe and sustainable level of OTEC-generated electricity powering DACCS for 70 years could result in up to a 35% decrease in the relative global mean temperature warming compared to a business-as-usual emissions scenario.

Key environmental predictors of Noctiluca scintillans distribution in the China sea and its climate change response.

Environmental pollution (Barking, Essex : 1987), 367:125672 pii:S0269-7491(25)00045-4 [Epub ahead of print].

Noctiluca scintillans is one of the most common harmful algal species worldwide. In this study, a MaxEnt model was constructed to calculate the present and future habitat suitability of N. scintillans in the China Sea. A comprehensive evaluation index of variable importance was defined to measure the importance of key predictors in the model, and offshore distance, long-term average minimum primary productivity, water depth, long-term average minimum temperature, and minimum salinity were determined as the dominant drivers. The HAB index that was constructed by integrating the carrying capacity and habitat suitability characteristics was used to measure the risk of harmful algal blooms (HABs). The index indicated that high-risk areas of HABs caused by N. scintillans occurred around Hainan Island, Taiwan Island, the coastal areas of Guangdong, Fujian, and Zhejiang provinces, and the eastern nearshore area of Weihai in Shandong. Regardless of the greenhouse gas emission scenario, the occurrence of N. scintillans red tides was predicted to persist until 2100. Moreover, the total area of the HABs high zone was predicted to increase under RCP2.6 and decrease under RCP8.5, and the center of the integrated HABs high zone was predicted to be concentrated in the central area of the entire China Sea spanning 15°N to 33°N.

Adaptation to Climate Change in Viticulture: The Role of Varietal Selection-A Review.

Plants (Basel, Switzerland), 14(1):.

Viticulture faces unprecedented challenges due to the rapidly changing climate, particularly in regions like the Mediterranean Basin. Consequently, climate change adaptation strategies are crucial in viticulture, with short-term strategies being widely used despite increasing concerns about their sustainability, and long-term strategies considered promising, though costly. A promising but understudied strategy is varietal selection, as grapevines exhibit vast intervarietal diversity with untapped potential for climate-resilient varieties. By integrating research across plant physiology, biochemistry, histology, and genetics, we can better understand the traits behind the grapevine's capability for adaptation. Several traits, including morphological, physiological, and molecular aspects, have been shown to be crucial in adapting to environmental stresses such as drought and heat. By studying the abundant grapevine intervarietal diversity, the potential for viticulture adaptation to climate change through varietal selection is immense. This review article focuses on the potential of varietal selection in the adaptation of viticulture to climate change. For this, we will delve into the research regarding how climate affects grapevine growth and grape quality and how the grapevine responds to stress conditions, followed by a summary of different climate change adaptation strategies of viticulture. Finally, we will focus on varietal selection, discussing and summarizing different studies surrounding grapevine variety behaviour.

Prediction of Potential Habitat Distributions and Climate Change Impacts on the Rare Species Woonyoungia septentrionalis (Magnoliaceae) in China Based on MaxEnt.

Plants (Basel, Switzerland), 14(1):.

Changes in species' habitats provide important insights into the effects of climate change. Woonyoungia septentrionalis, a critically endangered species endemic to karst ecosystems, has a highly restricted distribution and is a key biological resource. Despite its ecological importance, the factors influencing its habitat suitability and distribution remain poorly understood. This study employed ecological niche modeling to predict the potential distribution of Woonyoungia septentrionalis across China and analyzed shifts in centroid location to explore migration pathways under current and future climate scenarios. The model exhibited high predictive accuracy (AUC = 0.988), indicating its robustness in assessing habitat suitability. Under current climatic conditions, Woonyoungia septentrionalis is predominantly found in the Guizhou-Guangxi border region, southeastern Yunnan, eastern Sichuan, southeastern Tibet, and parts of Chongqing, Hunan, and Hubei. Among these, the Guizhou-Guangxi border represents the primary suitable habitat. Temperature factors, particularly bio6 (minimum temperature of the coldest month) and bio7 (annual temperature range), were the most significant determinants of habitat suitability, contributing 43.29% and 12.65%, respectively. Soil cation exchange capacity (CEC) accounted for 15.82%, while precipitation had a relatively minor impact. Under future climate scenarios, suitable habitats for Woonyoungia septentrionalis are projected to shrink and shift toward higher altitudes and latitudes, increasing the risk of extinction due to the "mountain trap" effect, where migration is constrained by limited habitat at higher elevations. Stable habitats, particularly in Libo (Guizhou) and Huanjiang (Guangxi), are identified as critical refugia. We recommend prioritizing shrinking and stable habitats in Guizhou, Guangxi, and Yunnan for in situ conservation. Ex situ conservation efforts should focus on areas identified based on key environmental factors and predicted migration pathways to ensure the species' long-term survival. This study provides both theoretical and practical guidance for the conservation of this species and its vulnerable habitat.

Predicting the Global Distribution of Nitraria L. Under Climate Change Based on Optimized MaxEnt Modeling.

Plants (Basel, Switzerland), 14(1):.

The genus of Nitraria L. are Tertiary-relict desert sand-fixing plants, which are an important forage and agricultural product, as well as an important source of medicinal and woody vegetable oil. In order to provide a theoretical basis for better protection and utilization of species in the Nitraria L., this study collected global distribution information within the Nitraria L., along with data on 29 environmental and climatic factors. The Maximum Entropy (MaxEnt) model was used to simulate the globally suitable distribution areas for Nitraria L. The results showed that the mean AUC value was 0.897, the TSS average value was 0.913, and the model prediction results were excellent. UV-B seasonality (UVB-2), UV-B of the lowest month (UVB-4), precipitation of the warmest quarter (bio18), the DEM (Digital Elevation Model), and annual precipitation (bio12) were the key variables affecting the distribution area of Nitraria L, with contributions of 54.4%, 11.1%, 8.3%, 7.4%, and 4.1%, respectively. The Nitraria L. plants are currently found mainly in Central Asia, North Africa, the neighboring Middle East, and parts of southern Australia and Siberia. In future scenarios, except for a small expansion of the 2030s scenario model Nitraria L., the potential suitable distribution areas showed a decreasing trend. The contraction area is mainly concentrated in South Asia, such as Afghanistan and Pakistan, North Africa, Libya, as well as in areas of low suitability in northern Australia, where there was also significant shrinkage. The areas of expansion are mainly concentrated in the Qinghai-Tibet Plateau to the Iranian plateau, and the Sahara Desert is also partly expanded. With rising Greenhouse gas concentrations, habitat fragmentation is becoming more severe. Center-of-mass migration results also suggest that the potential suitable area of Nitraria L. will shift northwestward in the future. This study can provide a theoretical basis for determining the scope of Nitraria L. habitat protection, population restoration, resource management and industrial development in local areas.

Characterizing Droughts During the Rice Growth Period in Northeast China Based on Daily SPEI Under Climate Change.

Plants (Basel, Switzerland), 14(1):.

In agricultural production, droughts occurring during the crucial growth periods of crops hinder crop development, while the daily-scale standardized precipitation evapotranspiration index (SPEI) can be applied to accurately identify the drought characteristics. In this study, we used the statistical downscaling method to obtain the daily precipitation (Pr), maximum air temperature (Tmax) and minimum air temperature (Tmin) during the rice growing season in Heilongjiang Province from 2015 to 2100 under the SSP1-2.6, SSP2-4.5 and SSP5-8.5 in CMIP6, to study the spatial and temporal characteristics of drought during the rice growing season in cold region and the effect of climate change on drought characteristics. The potential evapotranspiration (PET0) was calculated using the regression correction method of the Hargreaves formula recommended by the FAO, and the daily SPEI was calculated to quantitatively identify the drought classification. The Pearson correlation coefficient was used to analyze the correlation between the meteorological factors (Pr, Tmax, Tmin), PET0 and SPEI. The results showed that: (1) Under 3 SSP scenarios, Pr showed an increasing trend from the northwest to the southeast, Tmax showed an increasing trend from the northeast to the southwest, and higher Tmin was mainly distributed in the east and west regions. (2) PET0 indicated an overall interannual rise in the three future SSP scenarios, with higher values mainly distributed in the central and western regions. The mean daily PET0 values ranged from 4.8 to 6.0 mm/d. (3) Under SSP1-2.6, rice mainly experienced mild drought and moderate drought (-0.5 ≥ SPEI > -1.5). The predominant drought classifications experienced were mild, moderate, and severe drought under SSP2-4.5 and SSP8.5 (-0.5 ≥ SPEI > -2.0). (4) The tillering stage experienced the highest drought frequency and drought intensity, with the longest drought lasting 24 days. However, the heading flower stage had the lowest drought frequency and drought intensity. The drought barycenter was mainly in Tieli and Suihua. (5) The PET0 was most affected by the Tmax, while the SPEI was most affected by the Pr. This study offers a scientific and rational foundation for understanding the drought sensitivity of rice in Northeast China, as well as a rationale for the optimal scheduling of water resources in agriculture in the future.

Modeling Mastitis Risk Management Effects on Dairy Milk Yield and Global Warming Potential.

Animals : an open access journal from MDPI, 15(1):.

Mastitis represents a significant challenge for dairy farming, resulting in economic losses and environmental impacts. This study assesses a model for the evaluation of the impact of mastitis on dairy productivity and Global Warming Potential (GWP) under diverse management scenarios. The model considers a range of factors, including bedding materials, milking systems, health surveillance, and overcrowding. The results of the simulation demonstrate that effective management, encompassing the utilization of sand bedding, and the presence of an annual herd health monitoring plan have the potential to reduce the prevalence of mastitis and enhance milk yield by up to 10% in milking parlors and 7% in automatic milking systems. At the herd level, the GWP ranged from 1.37 to 1.78 kg CO2eq/kg Fat- and Protein-Corrected Milk (FPCM), with the use of sand bedding resulting in a 14% reduction in GWP, while the utilization of non-composted manure-based materials led to an increase of 12%. The occurrence of overcrowding and a lack of adequate cleanliness in resting areas were found to have a markedly detrimental impact on both productivity and the environmental performance of cows. These findings illustrate the dual benefits of enhanced mastitis management, namely improved milk production and reduced environmental impact. They offer valuable insights for farmers and policymakers alike.

The short-term comprehensive impact of the phase-out of global coal combustion on air pollution and climate change.

Environmental pollution (Barking, Essex : 1987), 367:125669 pii:S0269-7491(25)00042-9 [Epub ahead of print].

With the continuous intensification of global warming, the reduction and ultimate phase-out of coal combustion is an inevitable trend in the future global energy transformation. This study comprehensively analyzed the impact of phasing out coal combustion on global emissions and concentrations of air pollutants, radiative fluxes, meteorology and climate using Community Earth System Model 2 (CESM2). The results indicate that after the global phase-out of coal combustion, there is a marked decrease in the concentrations of sulfur dioxide (SO2), nitrogen oxides (NOx) and fine particulate matter (PM2.5), with some regions experiencing a reduction of exceeding 50%. There is no significant change in global ozone (O3) concentration. There are decreasing AOD and positive radiative fluxes globally in the short term, though the cloud contributes minor negative radiative fluxes. The global air temperature may increase by approximately (0.02 ± 0.15) °C on average with regional and seasonal variations, and the precipitation may potentially increase by approximately (2.7 ± 40.6) mm yr[-1] globally and over 20% in equatorial regions in the short term. But combined with the decreasing trend of cloud water content in the Northern Hemisphere, it indicates a potential increase in the extremity of precipitation events. This study provides references for global control of air pollution, mitigation strategies of climate change, and transformation of energy structures under the objective of "carbon neutrality", such as focusing on the negative climate impacts of exacerbating regional warming and increasing extreme precipitation resulting from the rapid reduction of aerosols in the short term.

High-resolution assessment of climate change impacts on the surface energy and water balance in the glaciated Naryn River basin, Central Asia.

Journal of environmental management, 374:124021 pii:S0301-4797(24)04008-8 [Epub ahead of print].

Mountain regions of Central Asia are experiencing strong influences from climate change, with significant reductions in snow cover and glacial reserves. A comprehensive assessment of the potential consequences under the worst-case climate scenario is vital for adaptation measures throughout the region. Water balance analysis in the Naryn River basin was conducted for the baseline period of 1981-2000 including potential changes under the worst-case SSP5-8.5 scenario for 2077-2096 by combining high-resolution (5 km) regional climate projections with fully distributed glacio-hydrological (1 km) modeling. Results showed that with the complete degradation of glaciers and increase in evapotranspiration, the overall runoff will decrease by 16%, and in the upper basins, the reduction will exceed 40%. The maximum snow water equivalent (SWE) is projected to decrease by 17%, and the seasonal peak of SWE will occur one month earlier. The transition from snow to rain will significantly affect lower regions, increasing extremes in peak runoff and causing 10-year recurrence interval events to occur every 3-4 years. Moreover, extreme runoff in high mountainous areas will increase due to intensified snowmelt and increased rainfall extremes. Additionally, a gradient of surface soil temperature change of 0.1 °C per 100 m elevation gain was observed, suggesting a potential snow-albedo feedback effect that could further amplify the warming, especially at higher altitudes. This study provides a robust analytical framework to assess the complex responses of mountain ecosystems to the impacts of climate change, with the potential of widespread application for addressing the challenges facing these critical regions.

Impact of climate change on permanent lakes in a semiarid region: Southwestern Mediterranean basin (S Spain).

The Science of the total environment, 961:178305 pii:S0048-9697(24)08463-8 [Epub ahead of print].

In recent decades, many wetlands in the Mediterranean watershed have dried up. We forecast the impact of climate change on the hydrology of three permanent lakes in a semiarid areo of the southwestern Mediterranean region. To achieve this, we applied daily water balance models to calculate variations in water levels and validated our approach using actual lake level measurements spanning over 20 years. To delve into groundwater/lake interactions, we calculated several hydrological indices and compared evaporation with the water level drop during extremely dry periods. After validating the three hydrological models, we applied the RCP 4.5 and RCP 8.5 climate change scenarios. We found Zóñar Lake highly resilient to climate changes because of groundwater contributions, resulting in minimal lake level oscillations even during periods of low rainfall. However, spring management and/or groundwater extractions may affect the lake hydroperiod. The Amarga and Grande lakes have weaker lake/groundwater interactions and show significant water lake level fluctuations, making them more sensitive to climate change. Indeed, our model predict that these lakes will transition into semipermanent or seasonal playa-lakes by mid-21th century. We found that deep and spring and/or groundwater-fed lakes are less vulnerable to climate changes. These results highlight the importance of developing robust hydrogeological models in such water bodies, focusing on the climate changes vulnerability of wetlands in semiarid regions, in order to formulate an integrated strategy for water resources management.

Climate change could amplify weak synchrony in large marine ecosystems.

Proceedings of the National Academy of Sciences of the United States of America, 122(1):e2404155121.

Climate change is increasing the frequency of large-scale, extreme environmental events and flattening environmental gradients. Whether such changes will cause spatially synchronous, large-scale population declines depends on mechanisms that limit metapopulation synchrony, thereby promoting rescue effects and stability. Using long-term data and empirical dynamic models, we quantified spatial heterogeneity in density dependence, spatial heterogeneity in environmental responses, and environmental gradients to assess their role in inhibiting synchrony across 36 marine fish and invertebrate species. Overall, spatial heterogeneity in population dynamics was as important as environmental drivers in explaining population variation. This heterogeneity leads to weak synchrony in the California Current Ecosystem, where populations exhibit diverse responses to shared, large-scale environmental change. In contrast, in the Northeast U.S. Shelf Ecosystem, gradients in average environmental conditions among locations, filtered through nonlinear environmental response curves, limit synchrony. Simulations predict that environmental gradients and response diversity will continue to inhibit synchrony even if large-scale environmental extremes become common. However, if environmental gradients weaken, synchrony and periods of large-scale population decline may rise sharply among commercially important species on the Northeast Shelf. Our approach thus allows ecologists to 1) quantify how differences among local communities underpin landscape-scale resilience and 2) identify the kinds of future climatic changes most likely to amplify synchrony and erode species stability.

Studying attention to IPCC climate change maps with mobile eye-tracking.

PloS one, 20(1):e0316909.

Many visualisations used in the climate communication field aim to present the scientific models of climate change to the public. However, relatively little research has been conducted on how such data are visually processed, particularly from a behavioural science perspective. This study examines trends in visual attention to climate change predictions in world maps using mobile eye-tracking while participants engage with the visualisations. Our primary aim is to assess engagement with the maps, as indicated by gaze metrics. Secondary analyses assess whether social context (as social viewing compared to solitary viewing) affects these trends, the relationship between projection types and visual attention, compare gaze metrics between scientific map and artwork viewing, and explore correlations between self-reported climate anxiety scores and attention patterns. We employed wearable, head-mounted eye-tracking to collect data in relatively naturalistic conditions, aiming to enhance ecological validity. In this research, participants engaged with ten world maps displaying near- and far-term climate projections across five data categories, adapted from the online interactive atlas provided by the International Panel on Climate Change (IPCC). To compare scientific information processing with aesthetic perception, participants also viewed two large-scale artworks. Responses to the Climate Change Anxiety Scale (CCAS) were also collected. Participants viewed the displays alone (single-viewing condition, N = 35) or together with a partner (paired-viewing condition, N = 12). Results revealed that the upper parts of the maps, particularly the continental Europe, received significant attention, suggesting a Euro-centric bias in viewing patterns. Spatial gaze patterns were similar between single and paired conditions, indicating that the visual attributes of the maps predominantly shaped attention locations. Although dwell times were comparable, the paired condition showed higher fixation counts, shorter average fixation durations, and longer scanpaths, suggesting a potentially dissociable viewing strategy and more exploratory viewing patterns influenced by social interaction. No substantial differences were observed in attention across projection timeframes or types, although individual variations were noted. Artwork viewing exhibited notably shorter average fixation durations compared to climate map viewing, potentially reflecting different visual engagement styles. Despite positive linear correlations among the four CCAS subscales, there was no apparent correlation between CCAS scores and main gaze metrics, indicating a lack of a direct relationship between self-reported anxiety and gaze behaviour. In summary, visual attention to climate change visualisations appears to be mainly influenced by the inherent visual attributes of the maps, but the social context may subtly influence visual attention. Additionally, the comparison with aesthetic viewing highlights relatively distinct attentional patterns in scientific versus aesthetic engagements.

Research progress on the impact of climate change on wheat production in China.

PeerJ, 13:e18569.

It is crucial to elucidate the impact of climate change on wheat production in China. This article provides a review of the current climate change scenario and its effects on wheat cultivation in China, along with an examination of potential future impacts and possible response strategies. Against the backdrop of climate change, several key trends emerge: increasing temperature during the wheat growing season, raising precipitation, elevated CO2 concentration, and diminished radiation. Agricultural disasters primarily stem from oscillations in temperature and precipitation, with the northern wheat region being mostly affected. The impact on wheat production is manifested in a reduction in the area under cultivation, with the most rapid reduction in spring wheat, and a shift in the center of cultivation to the west. Furthermore, climate change accelerates the nutritional stage and shortens phenology. Climate change has also led to an increase in yields in the Northeast spring wheat region, the Northern spring wheat region, the Northwest spring wheat region, and the North China winter wheat region, and a decrease in yields in the middle and lower reaches of the Yangtze River winter wheat region, the Southwest winter wheat region, and the South China winter wheat region. To cope with climate change, Chinese wheat can adopt adaptation strategies and measures such as breeding different wheat varieties for different wheat-growing regions, implementing differentiated farmland management measures, promoting regional ecological farmland construction, and establishing scientific monitoring and early warning systems. While future climate change may stimulate wheat yield potential, it could cause climate-induced issues such as weeds, diseases, and pests worsen, thereby posing challenges to the sustainability of farmland. Moreover, it is essential to conduct comprehensive research on pivotal areas such as the microscopic mechanism of climate change and wheat growth, the comprehensive influence of multiple climate factors, and the application of new monitoring and simulation technologies. This will facilitate the advancement of related research and provide invaluable insights.

Unraveling climate change-induced compound low-solar-low-wind extremes in China.

National science review, 12(1):nwae424.

China's pursuit of carbon neutrality targets hinges on a profound shift towards low-carbon energy, primarily reliant on intermittent and variable, yet crucial, solar and wind power sources. In particular, low-solar-low-wind (LSLW) compound extremes present a critical yet largely ignored threat to the reliability of renewable electricity generation. While existing studies have largely evaluated the impacts of average climate-induced changes in renewable energy resources, comprehensive analyses of the compound extremes and, particularly, the underpinning dynamic mechanisms remain scarce. Here we show the dynamic evolution of compound LSLW extremes and their underlying mechanisms across China via coupling multi-model simulations with diagnostic analysis. Our results unveil a strong topographic dependence in the frequency of compound LSLW extremes, with a national average frequency of 16.4 (10th-90th percentile interval ranges from 5.3 to 32.6) days/yr, when renewable energy resources in eastern China are particularly compromised (∼80% lower than that under an average climate). We reveal a striking increase in the frequency of LSLW extremes, ranging from 12.4% under SSP126 to 60.2% under SSP370, primarily driven by both renewable energy resource declines and increasingly heavily-tailed distributions, resulting from weakened meridional temperature (pressure) gradient, increased frequency of extremely dense cloud cover and additional distinctive influence of increased aerosols under SSP370. Our study underscores the urgency of preparing for significantly heightened occurrences of LSLW events in a warmer future, emphasizing that such climate-induced compound LSLW extreme changes are not simply by chance, but rather projectable, thereby underscoring the need for proactive adaptation strategies. Such insights are crucial for countries navigating a similar transition towards renewable energy.

Climate change mitigation potential and economic evaluation of selected technical adaptation measures and innovations in conventional arable farming in Germany.

Journal of environmental management, 374:123884 pii:S0301-4797(24)03871-4 [Epub ahead of print].

Agriculture accounts for a large proportion of global greenhouse gas (GHG) emissions. It is therefore crucial to identify effective and efficient GHG mitigation potentials in agriculture, but also in related upstream sectors. However, previous studies in this area have rarely undertaken a cross-sectoral assessment. There is also a gap in research on the GHG mitigation potential of innovations such as green ammonia in arable farming at a larger spatial scale. The study therefore aimed to analyze how selected technological adaptations or innovations can be used to contribute to efficient and effective cross-sectoral GHG mitigation in conventional arable farming systems. Germany, one of the largest agricultural producers and contributors of GHG emissions from agriculture in the EU, was chosen as a case study. The GHG mitigation potential and abatement cost of four selected measures were analyzed using an integrated land use model and life cycle assessment. Their GHG mitigation potential varied between 0.3 Mt CO2-eq. for nitrification inhibitors under lower mitigation rate assumptions and 4.7 Mt CO2-eq. for green ammonia with upper mitigation rate assumptions on GHG emission impacts, i. e. rather high mitigation. While crop varieties based on new genomic technologies (NGT) were introduced at no GHG abatement cost, the average mitigation costs ranged from 48 € for the use of nitrification inhibitors (upper mitigation rate) to 1233 € per t CO2-eq. for N sensors (lower mitigation rate). There were also regional differences due to different land use structures, regional farm sizes, economic and agronomic conditions. Based on these results we recommend for agricultural and environmental policy to foster the use of nitrification inhibitors due to the identified GHG reduction potential and the comparatively low GHG abatement costs. Additionally, the use of green ammonia in fertilizer production should be further promoted. Although the results are exemplary for Germany, they can be very informative for other EU Member States with comparable socio-economic and agronomic conditions.

Grazing can reduce wildfire risk amid climate change.

Science (New York, N.Y.), 387(6730):eadu7471.

Over half of Earth's land surface is covered with fire-prone vegetation, with grassy ecosystems-such as grasslands, savannas, woodlands, and shrublands-being the most extensive. In the context of the climate crisis, scientists worldwide are exploring adaptation measures to address the heightened fire risk driven by more frequent extreme climatic conditions such as droughts and heatwaves, as well as by non-native plant invasions that increased fuel loads and altered fire regimes. Although fire is intrinsic to grassy ecosystems, rising exposure to wildfire smoke harms human health and the environment. Here, we argue that grazing management in grassy ecosystems could help reduce wildfire risk and its consequences.

Changing pattern of urban landscape and its impact on thermal environment of Lahore; Implications for climate change and sustainable development.

Environmental monitoring and assessment, 197(2):151.

Rapid urbanization in Lahore has dramatically transformed land use and land cover (LULC), significantly impacting the city's thermal environment and intensifying climate change and sustainable development challenges. This study aims to examine the changes in the urban landscape of Lahore and their impact on the Urban thermal environment between 1990 and 2020. The previous studies conducted on Lahore lack the application of Geospatial artificial intelligence (GeoAI) to quantify land use and land cover, which is successfully covered in this study. This study analyzes how urban sprawl has driven LULC shifts and assesses their direct impact on Land Surface Temperature (LST) using Geographic Information System (GIS) and remote sensing techniques. Landsat imagery, processed using Google Earth Engine (GEE), was employed for LULC classification and LST calculation, ensuring high accuracy through multi-level change detection and a thorough accuracy assessment. Pearson's correlation was also calculated in this study to assess the impact of decreased green cover on LST. The findings highlight a substantial decrease in green cover, from 1,292.8 km[2] in 1990 to 754 km[2] in 2020, alongside a marked increase in built-up areas, expanding from 262 km[2] to over 550 km[2]. Additionally, barren land showed significant growth, while water bodies diminished. The spatiotemporal analysis of LST indicates a considerable rise in high-temperature zones, specifically the industrial zones, with areas exceeding 40 °C expanding from 2 km[2] to 1,075 km[2] over the study period. A strong positive correlation between increased urbanization and rising LST, particularly in areas within a 10 to 40 km radius of the Central Business District (CBD), is evident. The overall accuracy of LULC classification surpassed 94%, with the kappa coefficient above 92%, ensuring the robustness of the results. Future research should focus on evaluating the long-term socioeconomic impacts of urban sprawl and LST increment while developing heat mitigation strategies. Recommendations include adopting sustainable urban planning practices prioritizing green infrastructure, energy-efficient building designs, and policies promoting environmental preservation. This study offers valuable insights for policymakers and underscores the urgency of balancing urban growth with strategies that mitigate thermal stress, combat climate change, and foster sustainable development in Lahore.

Influence of global warming and human activity on mercury accumulation patterns in wetlands across the Qinghai-Tibet Plateau.

National science review, 12(1):nwae414.

Wetlands in the Qinghai-Tibet Plateau are a unique and fragile ecosystem undergoing rapid changes. We show two unique patterns of mercury (Hg) accumulation in wetland sediments. One is the 'surface peak' in monsoon-controlled regions and the other is the 'subsurface peak' in westerly-controlled regions. The former is attributed to the combined effects of increasing anthropogenic emissions and climate-induced changes in the cryosphere and wetland hydrology in the last 100-150 years. The climate changes in westerly-controlled regions in the last 50-70 years led to a fluctuation in hydrology and Hg peak in the sediment subsurface. The increase in legacy Hg input from soil erosion has largely enhanced the Hg accumulation rate in wetlands since the 1950s, especially in the proglacial wetlands. We highlight that accelerated glacier melting and permafrost thawing caused by global warming have altered geomorphology and hydrology, and affected Hg transport and accumulation in wetlands.

Intertwined people-nature relations are central to nature-based adaptation to climate change.

Philosophical transactions of the Royal Society of London. Series B, Biological sciences, 380(1917):20230213.

Adaptation to climate change is a social-ecological process: it is not solely a result of natural processes or human decisions but emerges from multiple relations within social systems, within ecological systems and between them. We propose a novel analytical framework to evaluate social-ecological relations in nature-based adaptation, encompassing social (people-people), ecological (nature-nature) and social-ecological (people-nature) relations. Applying this framework to 25 case studies, we analyse the associations among these relations and identify archetypes of social-ecological adaptation. Our findings revealed that adaptation actions with more people-nature relations mobilize more social and ecological relations. We identified four archetypes, with distinct modes of adaptation along a gradient of people-nature interaction scores, summarized as: (i) nature control; (ii) biodiversity-based; (iii) ecosystem services-based; and (iv) integrated approaches. This study contributes to a nuanced understanding of nature-based adaptation, highlighting the importance of integrating diverse relations across social and ecological systems. Our findings offer valuable insights for informing the design and implementation of adaptation strategies and policies.This article is part of the discussion meeting issue 'Bending the curve towards nature recovery: building on Georgina Mace's legacy for a biodiverse future'.

Indigenous university students' perceptions regarding nature, their daily lives and climate change: a photovoice study.

BMC public health, 25(1):90.

BACKGROUND: Climate change has severe health impacts, particularly for populations living in environmentally sensitive areas such as riversides, slopes, and forests. These challenges are exacerbated for Indigenous communities, who often face marginalisation and rely heavily on the land for their livelihoods. Despite their vulnerability, the perspectives of Indigenous populations on climate change and its impacts remain underexplored, creating a critical gap in the literature. This study explored the perceptions of Indigenous Brazilian university students on how climate change affects their daily lives and gathered their insights on potential adaptations to mitigate climate change-related impacts.

METHODS: Using a participatory arts-based approach, participants captured photographs reflecting their lived experiences with climate change. Follow-up interviews provided a narrative framework for qualitative analysis, enabling participants to articulate the strengths and concerns of their communities while transcending cultural and linguistic barriers.

RESULTS: The study revealed key themes, including (1) the fragility of ecosystems critical to Indigenous livelihoods, (2) the erosion of traditional knowledge systems due to environmental and social disruptions, and (3) the need for community-driven strategies to protect territories and preserve cultural identities. Participants highlighted the interconnectedness of their cultural values with environmental stewardship, emphasising the importance of maintaining these relationships as a form of resilience.

CONCLUSION: This study underscores the importance of protecting Indigenous territories and respecting their cultural identities to safeguard their survival and traditions. The voices of Indigenous university students provided valuable insights into community-based adaptations and strategies for mitigating the impacts of climate change.

OBJECTIVE: The primary objective was to assess pharmacy educators' beliefs regarding climate change and whether its effects on health should be included in Doctor of Pharmacy curricula. Secondary objectives were to identify potential barriers, helpful materials, and current and future tactics to provide this content.

METHODS: An electronic survey was sent to faculty and administrators of U.S.-based, fully-accredited Doctor of Pharmacy programs (n = 139) in February 2024 collecting opinions and demographic information.

RESULTS: A total of 764 usable surveys were completed, representing 135 programs. Nearly 87 % of respondents thought climate change is happening. More thought climate change harms human health (74.7 %) than thought climate change was relevant to pharmacists/pharmacy practice (51.6 %, p < 0.001) or pharmaceutical scientists/pharmaceutical sciences (57.2 %, p < 0.001). Perceived importance of including specific topics in pharmacy education ranged from 58 % (loss of biodiversity) to 80 % (disaster preparedness/response). Respondents indicated they would be most likely to use case studies (61.2 %) and active learning exercises (57.5 %) if they were available. Ninety-seven percent perceived at least one challenge to incorporating climate change and health in curricula.

CONCLUSIONS: There is a need to increase knowledge and awareness among pharmacy educators regarding the connection between climate change, health, and pharmacy practice to prepare student pharmacists to protect public health.

Global mental health (Cambridge, England), 11:e118.

Climate anxiety has a negative impact on the mental health and psychological well-being of the vulnerable population. The goal is to assess many factors that affect mental health and psychological well-being, as well as how climate change affects mental health in Pakistan's vulnerable population. This study provides evidence-based insights into the long- and medium-term impacts of extreme weather events on mental health. To obtain information on these variables, this research uses a quantitative approach and a cross-sectional survey design with a multivariate regression model for empirical tests on a sample of parents and children with an impact on mental health from climate change anxiety. Results indicate that individuals who experience shock climate change anxiety and its effects on mental health and psychological well-being. Climate change can have detrimental effects on children's mental health. (1) Children's Stress Index (CSI): (2) climate change anxiety (CCA), (3) generalised anxiety disorder (GAD) and (4) major depression disorder (MDD), as reported by the children with mental health outcomes. The findings of this study show that climate change has a stressful effect on mental health. The article concludes with a discussion on strategies to address the anticipated mental health issues among children due to climate change.

Fatal Sarcoptes scabiei and Demodex sp. co-infestation in wolves (Canis lupus) at the Białowieża National Park, Poland - is it a consequence of climate change?.

Journal of veterinary research, 68(4):551-562.

INTRODUCTION: In winter 2021/2022, a wolf population in the primeval Białowieża Forest in Poland was struck by an outbreak of severe mange caused by mixed infestations of Sarcoptes and Demodex mites. We present an epidemiological analysis of this mange which caused significant morbidity and mortality.

MATERIAL AND METHODS: Ten sites known for wolf activity were monitored by camera trapping. A diagnostic necropsy and testing of a young wolf was performed to determine the causes of death.

RESULTS: Five young wolves with severe alopecia of the entire body and some other individuals with minor to medium mange lesions were identified by the camera surveillance. The necropsy of the carcass revealed emaciation, dehydration and anaemia with starvation as the cause of death, likely attributable to severe infestation with Sarcoptes scabiei and Demodex sp. mites. Rabies and infections with Borreliella sp., Anaplasma sp., Ehrlichia sp., Francisella tularensis, Babesia sp. and tick-borne encephalitis virus were excluded by specific tests.

CONCLUSIONS: The described analysis is the first documented co-infestation of this kind in wolves. The outbreak coincided with very mild winter conditions with a high average minimum temperature, which may have favoured mite survival outside the host, and light snowfall, which may have influenced the wolves' ability to hunt. Other potential drivers of the outbreak could be the large proportion of wetland terrain, increasing number of wolves in the area and anthropogenic pressure on their habitats including the migration crisis at the Polish-Belarusian border and the increased presence of military and border forces, even despite the relief from the anthropogenic pressure from tourism due to the COVID-19 lockdown.

Differences in phenological term changes in field crops and wild plants - do they have the same response to climate change in Central Europe?.

International journal of biometeorology [Epub ahead of print].

Phenological shifts in wild-growing plants and wild animal phenophases are well documented at many European sites. Less is known about phenological shifts in agricultural plants and how wild ecosystem phenology interacts with crop phenology. Here, we present long-term phenological observations (1961-2021) from the Czech Republic for wild plants and agricultural crops and how the timing of phenophases differs from each other. The phenology of wild-growing plants was observed at various experimental sites with no agriculture or forestry management within the Czech Hydrometeorological Institute observations. The phenological data of the crops were collected from small experimental plots at the Central Institute for Supervising and Testing in Agriculture. The data clearly show a tendency to shift to earlier times during the observation period. The data also show some asynchrony in phenological shifts. Compared with wild plants, agricultural crops showed more expressive shifts to the start of the season. Phenological trends for crop plants (Triticum aestivum) showed accelerated shifts of 4.1 and 5.1 days per decade at low and middle altitudes, respectively; on the other hand, the average phenological shift for wild plants showed smaller shifts of 2.7 and 2.9 days per decade at low and middle altitudes, respectively. The phenophase ´heading´ of T. aestivum showed the highest correlation with maximum temperatures (r = 0.9), followed by wild species (with r = 0.7-0.8) and two remaining phenophases of T. aestivum jointing and ripening (with r = 0.7 and 0.6). To better understand the impacts of climate on phenological changes, it is optimal to evaluate natural and unaffected plant responses in wild species since the phenology of field crops is most probably influenced not only by climate but also by agricultural management.

[Climate change and ocular surface diseases].

Die Ophthalmologie [Epub ahead of print].

BACKGROUND: The ocular surface is directly exposed to environmental influences. Noxae that have already been identified for the ocular surface are heat, air dryness, pollutant gases, fine dust particles and ultraviolet radiation.

METHODS: The current literature was used to investigate the relationship between frequent ocular surface diseases and various environmental factors and to analyze their development over the years.

RESULTS: Epidemiological studies on dry eye disease and allergic conjunctivitis have shown an increase in the incidences in recent years. Environmental pollutants have been identified as disease triggers. In addition, the prolonged pollen season and increased pollen concentrations are also risk factors. There is also a higher prevalence of pterygium in population groups with high UV exposure. Other diseases with potential environmental pathogenesis are acute photokeratitis, photoconjunctivitis and malignant melanoma of the conjunctiva.

CONCLUSION: For ocular surface diseases, large epidemiological cohorts have shown climate-related increases in the incidence. A further increase in environmentally associated noxious substances can be expected in the coming decades. In addition to measures to mitigate climate change, the underlying mechanisms of disease development and new approaches to prevention and treatment, such as room humidification, air filters or contact lenses with UV filters, should be investigated.

Effect of temperature on circadian clock functioning of trees in the context of global warming.

The New phytologist [Epub ahead of print].

Plant survival in a warmer world requires the timely adjustment of biological processes to cyclical changes in the new environment. Circadian oscillators have been proposed to contribute to thermal adaptation and plasticity. However, the influence of temperature on circadian clock performance and its impact on plant behaviour in natural ecosystems are not well-understood. We combined bioinformatics, molecular biology and ecophysiology to investigate the effects of increasing temperatures on the functioning of the circadian clock in two closely related tree species from Patagonian forests that constitute examples of adaptation to different thermal environments based on their altitudinal profiles. Nothofagus pumilio, the species from colder environments, showed a major rearrangement of its transcriptome and reduced ability to maintain rhythmicity at high temperatures compared with Nothofagus obliqua, which inhabits warmer zones. In altitude-swap experiments, N. pumilio, but not N. obliqua, showed limited oscillator function in warmer zones of the forest, and reduced survival and growth. Our findings show that interspecific differences in the influence of temperature on circadian clock performance are associated with preferred thermal niches, and to thermal plasticity of seedlings in natural environments, highlighting the potential role of a resonating oscillator in ecological adaptation to a warming environment.

Climate change and the planned relocation of people: A longitudinal analysis of Vunidogoloa, Fiji.

Ambio [Epub ahead of print].

Rising sea levels under a changing climate will cause permanent inundation, flooding, coastal erosion, and saltwater intrusion. An emerging adaptation response is planned relocation, a directed process of relocating people, assets, and infrastructure to safer locations. Climate-related planned relocation is an unfolding process, yet no longitudinal studies have examined outcomes over time. Vunidogoloa, a low-lying coastal village in Fiji, relocated to higher land in 2014. This paper considers the dynamic outcomes of relocation, based on qualitative data collected between 2015 and 2023. It examines: residents' changing experience of climate and environmental risk; governance and decision-making processes over time; improved access to many resources and services along with incomplete infrastructure; opportunities and threats to health; and changing social organization and place-based values. The paper foregrounds change over time and provides in-depth examination of dynamic planned relocation experiences and (mal)adaptation outcomes in Vunidogoloa, Fiji.

The impact of climate change on the nearly threatened taxa Elaeocarpus munroi (Wight) Mast. inhabiting in the forest of the Western Ghats.

Environmental monitoring and assessment, 197(2):146.

Elaeocarpus munroi (Wight) Mast., commonly called Nilgiri Marble Tree, is a nearly threatened taxa as per the International Union for Conservation of Nature (IUCN). This species is endemic to the southern Western Ghats. The present study examines its spatial distribution across the sky islands of the Western Ghats under different climate scenarios (1900-2100) using four shared socioeconomic pathways (SSPs). Species distribution modeling was conducted using ensemble techniques in R, along with various ecological niche modeling algorithms. The present study examines the past, present, and future distribution of E. munroi across the Western Ghats. Historical projections indicated that the highest habitat suitability areas for the species were in the southern and central regions of the Western Ghats. The model projections for the species from 2021 to 2100 indicate a noticeable northward shift in habitat suitability. As climate scenarios change, the central and northern regions of the Western Ghats are becoming more suitable for it. This anticipated shift poses a potential threat to the species persistence, as the availability of suitable habitats decline in its historically preferred southern range. This range shift, coupled with E. munroi's near-threatened status, emphasizes the urgent need for its conservation interventions. This study pioneers efforts to understand and mitigate the impacts of climate change on E. munroi. This, in turn, offers a foundation for developing targeted conservation strategies in this ecologically important region. The findings highlight the importance of integrating climate change into conservation planning and management practices to safeguard the future of species like E. munroi within the broader ecosystem they inhabit. This study contributes to the growing body of research addressing the complex interplay between climate change and biodiversity conservation, thereby underscoring the need for collaborative and proactive approaches to mitigate the adverse effects of climate change.

Integrating Pollutant registers for the climate change risk evaluation of industrial companies in Australia, Europe and North America.

Scientific reports, 15(1):1207.

We present a methodology to develop the integrated climate change transition and physical risk assessment of industrial companies in Europe, Northern America and Australia. There is an increasingly important need for effective large-scale climate change risk assessment solutions with more governments aligning their company reporting regulations with the Task Force on Climate-related Financial Disclosures recommendations. In this paper, we measure key aspects of climate change risks of industrial firms on the globe and vice versa. The study provides valuable insights into climate risk exposure for companies, investors, and consumers, offering a pioneering approach by integrating data from major international registers. We analyse data from 70,000 companies and their 170,000 plants, which report to fragmented Pollutant Release and Transfer Registers and Greenhouse Gas Reporting Programs. For our assessment, transition risks are measured in terms of reported greenhouse gas emissions, while physical risks calculated for all company plant locations in terms of historical cooling energy needs, flood exposure and photovoltaic power potential. We show that climate change transition and physical risks are not correlated, therefore climate change risks are variably felt across different factors. The research contributes to the evolving landscape of climate risk management and highlights the need for standardized methodologies in the face of impending regulatory changes.

Contributions of countries without a carbon neutrality target to limit global warming.

Nature communications, 16(1):468.

Bioenergy with carbon capture and storage (BECCS) is a key negative emission technology for climate mitigation. Some countries have made no commitment to carbon neutrality but are viewed as potential BECCS candidates (hereafter, non-CN countries). Here we analyze contributions of these countries to global climate mitigation with respect to BECCS using an Earth system model with explicit representations of bioenergy crops. Switchgrass cultivation in these non-CN countries can further remove atmospheric CO2 by 9.1 ± 2.8 and 19.9 ± 5.2 PgC in the low-warming and overshot scenarios, resulting in an extra biogeochemical cooling effect of 0.01 ± 0.04 to 0.02 ± 0.06 °C. This cooling is largely counterbalanced by the biophysical warming, but the net effect is still an extra cooling. The non-CN countries play a more important role in the low-warming scenario than in the overshoot scenario, despite the inequality of temperature change among countries. Our study highlights the importance of a global system for climate mitigation.

Genetic and morphological shifts associated with climate change in a migratory bird.

BMC biology, 23(1):3.

BACKGROUND: Rapid morphological change is emerging as a consequence of climate change in many systems. It is intuitive to hypothesize that temporal morphological trends are driven by the same selective pressures that have established well-known ecogeographic patterns over spatial environmental gradients (e.g., Bergman's and Allen's rules). However, mechanistic understanding of contemporary morphological shifts is lacking.

RESULTS: We combine morphological data and whole genome sequencing from a four-decade dataset in the migratory bird hermit thrush (Catharus guttatus) to test whether morphological shifts over time are accompanied by genetic change. Using genome-wide association, we identify alleles associated with body size, bill length, and wing length. Shifts in morphology and concordant shifts in morphology-associated alleles over time would support a genetic basis for the observed changes in morphology over recent decades, potentially an adaptive response to climate change. In our data, bill size decreases were paralleled by genetic shifts in bill size-associated alleles. On the other hand, alleles associated with body size showed no shift in frequency over time.

CONCLUSIONS: Together, our results show mixed support for evolutionary explanations of morphological response to climate change. Temporal shifts in alleles associated with bill size support the hypothesis that selection is driving temporal morphological trends. The lack of evidence for genetic shifts in body size alleles could be explained by a large role of plasticity or technical limitations associated with the likely polygenic architecture of body size, or both. Disentangling the mechanisms responsible for observed morphological response to changing environments will be vital for predicting future organismal and population responses to climate change.

Evolutionary adaptation under climate change: Aedes sp. demonstrates potential to adapt to warming.

Proceedings of the National Academy of Sciences of the United States of America, 122(2):e2418199122.

Climate warming is expected to shift the distributions of mosquitoes and mosquito-borne diseases, promoting expansions at cool range edges and contractions at warm range edges. However, whether mosquito populations could maintain their warm edges through evolutionary adaptation remains unknown. Here, we investigate the potential for thermal adaptation in Aedes sierrensis, a congener of the major disease vector species that experiences large thermal gradients in its native range, by assaying tolerance to prolonged and acute heat exposure, and its genetic basis in a diverse, field-derived population. We found pervasive evidence of heritable genetic variation in mosquito heat tolerance, and phenotypic trade-offs in tolerance to prolonged versus acute heat exposure. Further, we found genomic variation associated with prolonged heat tolerance was clustered in several regions of the genome, suggesting the presence of larger structural variants such as chromosomal inversions. A simple evolutionary model based on our data estimates that the maximum rate of evolutionary adaptation in mosquito heat tolerance will exceed the projected rate of climate warming, implying the potential for mosquitoes to track warming via genetic adaptation.

Wolbachia-Based Approaches to Controlling Mosquito-Borne Viral Threats: Innovations, AI Integration, and Future Directions in the Context of Climate Change.

Viruses, 16(12):.

Wolbachia-based mosquito control strategies have gained significant attention as a sustainable approach to reduce the transmission of vector-borne diseases such as dengue, Zika, and chikungunya. These endosymbiotic bacteria can limit the ability of mosquitoes to transmit pathogens, offering a promising alternative to traditional chemical-based interventions. With the growing impact of climate change on mosquito population dynamics and disease transmission, Wolbachia interventions represent an adaptable and resilient strategy for mitigating the public health burden of vector-borne diseases. Changes in temperature, humidity, and rainfall patterns can alter mosquito breeding habitats and extend the geographical range of disease vectors, increasing the urgency for effective control measures. This review highlights innovations in Wolbachia-based mosquito control and explores future directions in the context of climate change. It emphasizes the integration of Wolbachia with other biological approaches and the need for multidisciplinary efforts to address climate-amplified disease risks. As ecosystems shift, Wolbachia interventions could be crucial in reducing mosquito-borne diseases, especially in vulnerable regions. AI integration in Wolbachia research presents opportunities to enhance mosquito control strategies by modeling ecological data, predicting mosquito dynamics, and optimizing intervention outcomes. Key areas include refining release strategies, real-time monitoring, and scaling interventions. Future opportunities lie in advancing AI-driven approaches for integrating Wolbachia with other vector control measures, promoting adaptive, data-driven responses to climate-amplified disease transmission.

Predicting the Potential Distribution of Cheirotonus jansoni (Coleoptera: Scarabaeidae) Under Climate Change.

Insects, 15(12):.

Cheirotonus jansoni (Jordan, 1898), a beetle species of ecological and ornamental significance, is predominantly found in southern China. With limited dispersal ability, it is classified as a Class 2 protected species in China. In this study, the widely employed maximum entropy (MaxEnt) model and the ensemble Biomod2 model were applied to simulate C. jansoni habitat suitability in China under current environmental conditions based on available distribution data and multiple environmental variables. The optimized MaxEnt model demonstrated improved accuracy and robust predictive capabilities, making it the preferred choice for simulating dynamic changes in potentially suitable habitats for C. jansoni under future climate scenarios. Protection gaps were further identified through analyses of the overlap between nature reserves and highly suitable areas for C. jansoni. The established models indicated that this species primarily resides in southeastern mountainous regions of China below 2000 m, with a preferred altitude of 1000-2000 m. Future climate scenarios suggest a reduction in the overall suitable habitat for C. jansoni with an increase in temperature, underscoring the urgent need for enhanced conservation efforts for this beetle species.

Assessment of the Potential Suitable Habitat of Apriona rugicollis Chevrolat, 1852 (Coleoptera: Cerambycidae) Under Climate Change and Human Activities Based on the Biomod2 Ensemble Model.

Insects, 15(12):.

Effective use of species distribution models can assess the risk of spreading forest pests. In this study, based on 434 occurrence records and eight environmental variables, an ensemble model was applied to identify key environmental factors affecting the distribution of Apriona rugicollis Chevrolat, 1852 and predict its potential habitat and its relative areas of change under current and future climatic conditions. The results indicate that humidity, solar radiation, topography, and human activities were the main factors influencing the distribution of A. rugicollis. Under the current climate scenario, suitable habitats are mainly concentrated in East Asia, including North Korea, South Korea, Japan, Myanmar, Vietnam, and China. Under future climate scenarios, the area of suitable habitat for A. rugicollis gradually increases, especially in China and Japan, which are at high risk of spreading. In addition, the suitable habitat of A. rugicollis will expand northeastward to higher latitudes. The results of this study provide an important scientific basis for policymakers to formulate strategies for monitoring and controlling A. rugicollis in response to climate change.

Scoping Review of Climate Change Adaptation Interventions for Health: Implications for Policy and Practice.

International journal of environmental research and public health, 21(12):.

Climate change is among the greatest threats to health in the 21st century, requiring the urgent scaling-up of adaptation interventions. We aim to summarise adaptation interventions that were funded by the Belmont Forum and the European Union, the largest global funders of climate change and health research. A systematic search was conducted (updated February 2023) to identify articles on adaptation interventions for health within this funding network. The data extracted included study characteristics, types of interventions, and study outcomes. The results were synthesised narratively within the PRISMA-ScR guidelines. A total of 197 articles were screened, with 37 reporting on adaptation interventions. The majority of interventions focused on the general population (n = 17), with few studies examining high-risk populations such as pregnant women and children (n = 4) or migrants (n = 0). Targeted interventions were mostly aimed at behavioural change (n = 8) and health system strengthening (n = 6), while interventions with mitigation co-benefits such as nature-based solutions (n = 1) or the built environment (n = 0) were limited. The most studied climate change hazard was extreme heat (n = 26). Several studies reported promising findings, principally regarding interventions to counter heat impacts on workers and pregnant women and improving risk awareness in communities. These findings provide a platform on which to expand research and public health interventions for safeguarding public health from the effects of climate change.

Contributions of Medical Greenhouse Gases to Climate Change and Their Possible Alternatives.

International journal of environmental research and public health, 21(12): pii:ijerph21121548.

Considerable attention has recently been given to the contribution of the greenhouse gas (GHG) emissions of the healthcare sector to climate change. GHGs used in medical practice are regularly released into the atmosphere and contribute to elevations in global temperatures that produce detrimental effects on the environment and human health. Consequently, a comprehensive assessment of their global warming potential over 100 years (GWP) characteristics, and clinical uses, many of which have evaded scrutiny from policy makers due to their medical necessity, is needed. Of major interest are volatile anesthetics, analgesics, and inhalers, as well as fluorinated gases used as tamponades in retinal detachment surgery. In this review, we conducted a literature search from July to September 2024 on medical greenhouse gases and calculated estimates of these gases' GHG emissions in metric tons CO2 equivalent (MTCO2e) and their relative GWP. Notably, the anesthetics desflurane and nitrous oxide contribute the most emissions out of the major medical GHGs, equivalent to driving 12 million gasoline-powered cars annually in the US. Retinal tamponade gases have markedly high GWP up to 23,500 times compared to CO2 and long atmospheric lifetimes up to 10,000 years, thus bearing the potential to contribute to climate change in the long term. This review provides the basis for discussions on examining the environmental impacts of medical gases with high GWP, determining whether alternatives may be available, and reducing emissions while maintaining or even improving patient care.

Thermal Plasticity and Evolutionary Constraints in Bacillus: Implications for Climate Change Adaptation.

Biology, 13(12): pii:biology13121088.

The ongoing rise in global temperatures poses significant challenges to ecosystems, particularly impacting bacterial communities that are central to biogeochemical cycles. The resilience of wild mesophilic bacteria to temperature increases of 2-4 °C remains poorly understood. In this study, we conducted experimental evolution on six wild Bacillus strains from two lineages (Bacillus cereus and Bacillus subtilis) to examine their thermal adaptation strategies. We exposed the bacteria to gradually increasing temperatures to assess their thermal plasticity, focusing on the genetic mechanisms underlying adaptation. While B. subtilis lineages improved growth at highly critical temperatures, only one increased its thermal niche to 4 °C above their natural range. This finding is concerning given climate change projections. B. cereus strains exhibited higher mutation rates but were not able to grow at increasing temperatures, while B. subtilis required fewer genetic changes to increase heat tolerance, indicating distinct adaptive strategies. We observed convergent evolution in five evolved lines, with mutations in genes involved in c-di-AMP synthesis, which is crucial for potassium transport, implicating this chemical messenger for the first time in heat tolerance. These insights highlight the vulnerability of bacteria to climate change and underscore the importance of genetic background in shaping thermal adaptation.

Assessment of watershed health, integrating environmental, social, and climate change criteria into a fuzzy logic framework.

The Science of the total environment, 960:178316 pii:S0048-9697(24)08474-2 [Epub ahead of print].

Spatio-temporal analyses of environmental and social criteria in the context of climate change, facilitate understanding of how historical and current conditions have influenced watershed health. Previous studies have analyzed watershed health, but very few have integrated fuzzy logic with the CRITIC method (Criteria Importance Through Intercriteria Correlation), which enables us to explore alternatives to improve watershed performance. The objective of this study was to evaluate changes in watershed health through historical and projected climate change scenario in the tropical Santa Cruz watershed in Aquismón, S.L.P., Mexico (1985-2027) considering environmental criteria (hydrological and sediment connectivity, runoff, flooding, drought, landscape fragmentation) and social criteria (indigenous population density, human impact on biodiversity, health index, income index, education index). The results indicate that spatio-temporal changes can alter the Watershed Health Score (WHS) from a value of 2.69 to 6.90, particularly in areas with precarious social conditions. Moreover, the study reveals how weighting evolves overt time, as seen in the case of landscape fragmentation, whose value increased 0.0113 to 0.254. This study shows how objective methods such as CRITIC can be integrated through fuzzy logic to analyze the spatio-temporal evolution of watershed problems without the need for a large number of experts to weight the variables (subjective methods). This method can subsequently be applied and reproduced in different zones or watersheds where there is no certainty as to which criteria have the greatest influence and thus enable decisions for watershed management or restoration.

Climate Change Drives Changes in the Size and Composition of Fungal Communities Along the Soil-Seedling Continuum of Schima superba.

Molecular ecology [Epub ahead of print].

Plant microbiomes have a major influence on forest structure and functions, as well as tree fitness and evolution. However, a comprehensive understanding of variations in fungi along the soil-plant continuum, particularly within tree seedlings, under global warming is lacking. Here, we investigated the dynamics of fungal communities across different compartments (including bulk soil and rhizosphere soil) and plant organs (including the endosphere of roots, stems and leaves) of Schima superba seedlings exposed to experimental warming and drought using AccuITS absolute quantitative sequencing. Our results revealed that warming and drought significantly reduced the number of specific fungal amplicon sequence variants (ASVs) in the bulk soil and rhizosphere soil, respectively. Variations in fungal communities were mainly explained by compartments and plant organs, with the composition of endophytic fungal communities within leaves (primarily attributed to species gain or loss) being most influenced by climate change. Moreover, warming significantly reduced the migration of Ascomycota, soil saprotrophs, wood saprotrophs and yeasts from the bulk soil to the rhizosphere soil but increased that of plant pathogens from the roots to the stems. Drought significantly decreased the absolute abundances of Chytridiomycota, Glomeromycota and Rozellomycota, as well as the migration of ectomycorrhizal fungi from the bulk soil to the rhizosphere soil but increased that of plant pathogens. Warming could indirectly reduce leaf area by increasing the diversity of leaf pathogens. These findings have potential implications for enhancing the resilience and functioning of natural forest ecosystems under climate change through the manipulation of plant microbiomes, as demonstrated in agroecosystems.

Lung cancer in Asia: the impact of climate change.

EClinicalMedicine, 74:102680.

The escalating global threat of climate change is becoming more evident. The climate crisis intersects with another major challenge: lung cancer. With Asia already bearing half the global cancer burden, the impact of climate-related events on health and on lung cancer care specifically are profound. There can potentially be critical implications on the overall landscape of lung cancer care-from screening and early detection, to management and treatment. In 2022, the deadliest flooding events occurred in India and Pakistan. Extreme weather events such as cyclones and typhoons cause damage to healthcare facilities and disrupt transportation networks. These impede access to vital treatments, causing delays, thus worsening patients' conditions. Most low and middle-income countries (LMICs) have disparities in healthcare infrastructure, resources, and workforce distribution that result in limited access to comprehensive care. This fragmented healthcare system in many Asian countries pose additional challenges. Adaptation and mitigation strategies are crucial for minimizing these impacts on cancer care. Addressing this complex interplay demands urgent, collaborative, and multidisciplinary efforts to safeguard healthcare and ensure access to uninterrupted care amid climate-related challenges.

Climate change, migration, and health: perspectives from Latin America and the Caribbean.

Lancet regional health. Americas, 40:100926.

This article delves into the complex relationship between climate change, migration patterns, and health outcomes in Latin America and the Caribbean (LAC). While the severe impact of climate change on health in LAC is widely acknowledged, the article sheds light on the often-overlooked multiple effects on migration and the well-being of migrants. These impacts encompass poverty, food and water insecurity, and adverse physical and mental health outcomes. Our paper, guided by a rights-based framework, aims to identify key trends, challenges, and opportunities that can contribute to enhanced knowledge and generate questions to support future research. By emphasizing the need for collaborative efforts across sectors, including public and private entities, civil society, and academic institutions, we aim to address the nuanced intersections of climate change, migration, and health impacts in the region. This approach prioritises the needs of the most vulnerable, including migrants, establishing a framework for mitigation and adaptation that ensures equitable outcomes.

The need to (climate) adapt: perceptions of German sports event planners on the imperative to address climate change.

Frontiers in sports and active living, 6:1505372.

INTRODUCTION: While the impact of anthropogenic climate change on sports and the subsequent need for adaptation to evolving climatic conditions are acknowledged, there remains a notable paucity of scientific inquiry within the realm of sports and sports event studies specifically addressing climate change and its ramifications for event planning and management. Existing studies predominantly stem from health, medical, weather and climate science and mostly focus on mega-events and elite athlete contexts. Moreover, they often only focus on one specific impact (e.g., extreme heat) without providing a comprehensive summary or overview of all eminent impacts, resulting risks and potential adaptation strategies. This study aims to explore how (German) sports events are impacted by climate change and identify measures for organizers to address these impacts.

METHODS: Following a comprehensive literature review, semi-structured interviews with event planners and organizers in Germany were conducted, ranging from small local events to weekly league competitions to national championships and major events.

RESULTS: The findings demonstrate that climate change adaptation is not yet a primary focus in the German sports event context. While some planners, especially those of large-scale events, have started implementing adaptation measures, others are only beginning to address the issue.

DISCUSSION: The study discusses the challenges that sports event organizers face in adjusting to the adverse effects of climate change and also examines specific adaptation strategies. The paper emphasizes the imperative for organizers to incorporate climate adaptation measures more effectively into routine event planning and management processes, and provides practical guidelines to achieve this integration.

Indicators from The Lancet Countdown on Health and Climate Change: Perspectives and Experience of City Leaders from 118 Cities.

Journal of urban health : bulletin of the New York Academy of Medicine [Epub ahead of print].

Rapid urbanization and escalating climate crises place cities at the critical juncture of environmental and public health action. Urban areas are home to more than half of the global population, contributing ~ 75% of global greenhouse gas emissions. Structured surveys were completed by 191 leaders in city governments and civil society from 118 cities in 52 countries (February-April 2024). Data aggregated to report one response per city. The survey utilized framework and indicators established by The 2023 Lancet Countdown on Health and Climate Change. (1) Health hazards, exposures, impacts: two-thirds of cities identify extreme heat, flooding, and air pollution of "high concern," with health impacts for residents. (2) Adaptation, planning, resilience for health: Although 60% of cities have climate resilience plans, only 22.9% of cities have plans that concurrently address climate and health. Essential resources, municipal systems, and cross-sector collaborations are limited. (3) Mitigation actions and health co-benefits: 90% of cities reported air pollution from multiple sources; only 38% monitor air quality. Energy, food, and transportation systems are sub-optimal to mitigate climate concerns. (4) Economics and finance: 92% of cities report climate change-related economic losses; they plan to increase investments though resources remain constrained. (5) Public and political engagement: City leaders report minimal knowledge sharing among media, national/local government, scientific community, business community, and residents. Results underscore urgency for action and highlight solutions, providing a roadmap for cities to enhance resilience, safeguard public health, and promote social equity.

Editorial: Climate change is a children's health hazard.

Environmental research, health : ERH, 2(4):040201.

As temperatures defy heat records, it is difficult to ignore the implications of climate change for public health, including impacts on population health more specifically. In short, climate change is happening now and presents an immediate hazard to human health on a global scale. Age-related health effects are an inalienable truth; physiology is relatively universal, and so are the ways in which our bodies respond to different types and levels of exposures to environmental stressors at different lifestages. Children are uniquely vulnerable to climate change stressors not only due to their physical and developmental immaturity, but also because they generally rely on adult caretakers for the fundamentals of survival. This article is the summary piece accompanying a special issue of Environmental Research: Health. It compiles new studies on children's vulnerability to climate change as well as studies exploring climate adaptation strategies to promote and protect child health. In this special issue, we see how these concepts are reflected repeatedly in empirical data domestically and internationally. For example, the special issue includes articles investigating linkages between climate change and health hazards such as asthma, injuries, and malnutrition. While local context is extremely important, many of the health effects may be extrapolated to other communities around the world.

Using MaxEnt modeling to analyze climate change impacts on Pseudomonas syringae van Hall, 1904 distribution on the global scale.

Heliyon, 10(24):e41017.

Pseudomonas syringae is a pathogenic bacterium that poses a significant threat to global agriculture, necessitating a deeper understanding of its ecological dynamics in the context of global warming. This study investigates the current and projected future distribution of P. syringae, focusing on the climatic factors that influence its spread. To achieve this, we employed Maximum Entropy (MaxEnt) modeling based on Geographic Information Systems (GIS) to analyze species occurrence records alongside relevant climate data. The MaxEnt model was calibrated using 75 % of the occurrence data, with the remaining 25 % reserved for validation. The model's performance was meticulously assessed utilizing the area under the curve (AUC) and true skill statistics (TSS), resulting in an AUC score of 0.92, indicating excellent predictive capability. Our analysis identified key climatic parameters-temperature, precipitation, and humidity-that significantly affect the presence of P. syringae. Notably, our findings project an expansion of the bacterium's geographic range in the coming decades, with optimal conditions shifting toward the poles. This research underscores the significant influence of climate change on the distribution of P. syringae and provides valuable insights for developing targeted disease management strategies. The anticipated increase in bacterial infections in crops highlights the urgent need for proactive measures to mitigate these effects.

Estimation of GHGs emission from traditional kilns charcoal production in northwestern Ethiopia: Implications on climate change.

Heliyon, 10(24):e41015.

Rural areas in Ethiopia serve as the primary source of charcoal for urban populations, mainly produced using traditional kilns. However, this traditional method significantly contributes to greenhouse gas (GHG) emissions, exacerbating climate change and deforestation. While banning charcoal production is not currently feasible in Ethiopia because of the lack of affordable alternative energy sources (fuel), improving the efficiency of the traditional production system can mitigate the climate impact caused by charcoal production. This study assessed GHG emissions from traditional charcoal production in Awi zone, northwestern Ethiopia, using primary data from 18 sample kilns and secondary data from literature values. Employing a carbon balance approach, we estimated that, on average, 63 % of the original wood carbon was lost as gaseous products, resulting in 1671 g of carbon released per kg of charcoal produced in Awi zone. Our results also indicate that the average primary global warming impact (PGWI) for the 18 sample kilns was found to be 7.6 kg CO2-eq per kg of charcoal produced. Within this, the less efficient kiln production system, constituting 6 out of the sample, contributed 1.5 times more to global warming (9.43 kg CO2-eq per kg of charcoal produced) compared to the more efficient kiln system (6.25 kg CO2-eq per kg of charcoal produced for the same number of kilns). The policy implication of our finding is that any interventions aiming at mitigating climate change through reduction of GHG emissions from charcoal production must focus on improving the conversion efficiency of the traditional kiln currently used in addition to promoting the use of sustainably harvested wood.

Meta-analyses reveal climate change impacts on an ecologically and economically significant oyster in Australia.

iScience, 27(12):110673.

Global oceans are warming and acidifying because of increasing greenhouse gas emissions that are anticipated to have cascading impacts on marine ecosystems and organisms, especially those essential for biodiversity and food security. Despite this concern, there remains some skepticism about the reproducibility and reliability of research done to predict future climate change impacts on marine organisms. Here, we present meta-analyses of over two decades of research on the climate change impacts on an ecologically and economically valuable Sydney rock oyster, Saccostrea glomerata. We confirm with high confidence that ocean acidification (OA) has a significant impact on the size and mortality of offspring of S. glomerata, ocean warming (OW) impacts size, and transgenerational exposure of adults to OA has positive benefits for offspring. These meta-analyses reveal gaps in understanding of OW and transgenerational plasticity on an ecologically and economically significant oyster species to ensure sustainability of this iconic oyster in Australia.

Climate Change Influences via Species Distribution Shifts and Century-Scale Warming in an End-To-End California Current Ecosystem Model.

Global change biology, 31(1):e70021.

Climate change can impact marine ecosystems through many biological and ecological processes. Ecosystem models are one tool that can be used to simulate how the complex impacts of climate change may manifest in a warming world. In this study, we used an end-to-end Atlantis ecosystem model to compare and contrast the effects of climate-driven species redistribution and projected temperature from three separate climate models on species of key commercial importance in the California Current Ecosystem. Adopting a scenario analysis approach, we used Atlantis to measure differences in the biomass, abundance, and weight at age of pelagic and demersal species among six simulations for the years 2013-2100 and tracked the implications of those changes for spatially defined California Current fishing fleets. The simulations varied in their use of forced climate-driven species distribution shifts, time-varying projections of ocean warming, or both. In general, the abundance and biomass of coastal pelagic species like Pacific sardine (Sardinops sagax) and northern anchovy (Engraulis mordax) were more sensitive to projected climate change, while demersal groups like Dover sole (Microstomus pacificus) experienced smaller changes due to counteracting effects of spatial distribution change and metabolic effects of warming. Climate-driven species distribution shifts and the resulting changes in food web interactions were more influential than warming on end-of-century biomass and abundance patterns. Spatial projections of changes in fisheries catch did not always align with changes in abundance of their targeted species. This mismatch is likely due to species distribution shifts into or out of fishing areas and emphasizes the importance of a spatially explicit understanding of both climate change effects and fishing dynamics. We illuminate important biological and ecological pathways through which climate change acts in an ecosystem context and end with a discussion of potential management implications and future directions for climate change research using ecosystem models.

Climate change impact on water treatment plants: analysis of chlorophyll-a levels and process performance.

Environmental science and pollution research international [Epub ahead of print].

Climate change significantly impacts the risk of eutrophication and, consequently, chlorophyll-a (Chl-a) concentrations. Understanding the impact of water flows is a crucial first step in developing insights into future patterns of change and associated risks. In this study, the Statistical DownScaling Model (SDSM)-a widely used daily downscaling method-is implemented to produce downscaled local climate variables, which serve as input for simulating future hydro-climate conditions using a hydrological model. The vulnerability of water quality, particularly Chl-a concentrations in the Latyan Dam and Tehranpars Water Treatment Plant (TWTP) is assessed through six fuzzy regression models under three scenarios: RCP2.6, RCP4.5, and RCP8.5. Projections indicate an increase in minimum temperatures for the Jajrood watershed ranging from 92 to 93%. Seasonal forecasts suggest significant precipitation during the dry season. The HYMOD model predicts increases in streamflow of approximately 97%, 90%, and 92% by 2050 under RCP2.6, RCP4.5, and RCP8.5, respectively, indicating a heightened risk of flooding that poses economic, health, and environmental concerns. Among the six fuzzy regression models, FGR1, FGR3, and FGR4 demonstrated the most favorable results in modeling Chl-a output from the TWTP. In conclusion, while Chl-a concentrations in the effluent of the TWTP are only slightly influenced by climate change, the effects on streamflow patterns are significant. These findings highlight serious future water quality challenges and increased vulnerability of water resources due to climate change.

Integrated approach for estimating climate change impacts on CO2 sink capacity of inland waterbodies using hydrodynamic modelling and GIS analysis.

Scientific reports, 15(1):762.

As one of their key regulatory ecosystem functions, inland lakes serve as CO2 sinks. The CO2 sink capacity of inland lakes depends on their water temperature and salinity as well as their water volume which are all highly sensitive to climate conditions. This paper aims to quantitatively estimate the change in the CO2 sink capacity of Wadi El-Rayan Lakes under climate change scenarios. For this purpose, an integrated approach combining CO2 solubility modelling, hydrodynamic simulations (Delft3D-FLOW) and GIS analysis was employed. According to the developed approach, CO2 solubility under variable temperature and salinity is mathematically modelled and this model is further used with the developed hydrodynamic model data for Wadi El-Rayan Lakes (temperature, salinity and water depth) to estimate their CO2 sink capacities. CO2 sink capacity is estimated for 2014 and 2050 under two Representative Concentration Pathways (RCPs) 2.6 and 8.5. Afterwards, the alteration in CO2 sink capacities due to climate change is determined using the modified hydrodynamic model. The results revealed that by 2050, the lakes would lose about 23-25% of their capacities compared to that of 2014 according to RCP 2.6 and 8.5, respectively.

Ocean acidification and global warming may favor blue carbon service in a Cymodocea nodosa community by modifying carbon metabolism and dissolved organic carbon fluxes.

Marine pollution bulletin, 212:117501 pii:S0025-326X(24)01478-4 [Epub ahead of print].

Ocean acidification (OA) and global warming (GW) drive a variety of responses in seagrasses that may modify their carbon metabolism, including the dissolved organic carbon (DOC) fluxes and the organic carbon stocks in upper sediments. In a 45-day full-factorial mesocosm experiment simulating forecasted CO2 and temperature increase in a Cymodocea nodosa community, we found that net community production (NCP) was higher under OA conditions, particularly when combined with warming (i.e., synergistic effect). Moreover, under OA conditions, an increase in aboveground biomass and photosynthetic shoot area was recorded. Interestingly, DOC fluxes were reduced when exposed to OA; however, an increase occurred when both factors acted together (i.e., antagonistic effect), which was attributable to increased DOC release by plants. Our results suggest that C. nodosa populations in temperate latitude may favor blue carbon service in future scenarios of OA and GW by increasing the NCP, the DOC export with lower labile:recalcitrant ratio, and accumulating more organic carbon in upper sediments. These findings offer additional arguments for the urgent need to protect and conserve this valuable ecosystem.

Smallest microplastics intensify maize yield decline, soil processes and consequent global warming potential.

Journal of hazardous materials, 486:136993 pii:S0304-3894(24)03574-X [Epub ahead of print].

Microplastic pollution seriously affects global agroecosystems, strongly influencing soil processes and crop growth. Microplastics impact could be size-dependent, yet relevant field experiments are scarce. We conducted a field experiment in a soil-maize agroecosystem to assess interactions between microplastic types and sizes. Microplastics were added to soils used for maize cultivation: either polyethylene or polystyrene, of 75, 150, or 300 µm size. Overall, we found that microplastic contamination led to increased soil carbon, nitrogen and biogeochemical cycling. Polyethylene contamination was generally more detrimental than polystyrene. Smallest polyethylene microplastics (75 µm) were associated with two-fold raised CO2 and N2O emissions - hypothetically via raised microbial metabolic rates. Increased net greenhouse gases emissions were calculated to raise soil global warming potential of soils. We infer that MPs-associated emissions arose from altered soil processes. Polyethylene of 75 µm size caused the greatest reduction in soil carbon and nitrogen pools (1-1.5 %), with lesser impacts of larger microplastics. These smallest polyethylene microplastics caused the greatest declines in maize productivity (∼ 2-fold), but had no significant impact on harvest index. Scanning electron microscopy indicated that microplastics were taken up by the roots of maize plants, then also translocated to stems and leaves. These results raise serious concerns for the impact of microplastics pollution on future soil bio-geochemical cycling, food security and climate change. As microplastics will progressively degrade to smaller sizes, the environmental and agricultural impacts of current microplastics contamination of soils could increase over time; exacerbating potential planetary boundary threats.

Telomere Length Differences Indicate Climate Change-Induced Stress and Population Decline in a Migratory Bird.

Molecular ecology [Epub ahead of print].

Genomic projections of (mal)adaptation under future climate change, known as genomic offset, faces limited application due to challenges in validating model predictions. Individuals inhabiting regions with high genomic offset are expected to experience increased levels of physiological stress as a result of climate change, but documenting such stress can be challenging in systems where experimental manipulations are not possible. One increasingly common method for documenting physiological costs associated with stress in individuals is to measure the relative length of telomeres-the repetitive regions on the caps of chromosomes that are known to shorten at faster rates in more adverse conditions. Here we combine models of genomic offsets with measures of telomere shortening in a migratory bird, the yellow warbler (Setophaga petechia), and find a strong correlation between genomic offset, telomere length and population decline. While further research is needed to fully understand these links, our results support the idea that birds in regions where climate change is happening faster are experiencing more stress and that such negative effects may help explain the observed population declines.

Estimating forest aboveground carbon sink based on landsat time series and its response to climate change.

Scientific reports, 15(1):589.

Accurately estimating forest carbon sink and exploring their climate-driven mechanisms are critical to achieving carbon neutrality and sustainable development. Fewer studies have used machine learning-based dynamic models to estimate forest carbon sink. The climate-driven mechanisms in Shangri-La have yet to be explored. In this study, a genetic algorithm (GA) was used to optimize the parameters of random forest (RF) to establish dynamic models to estimate the carbon sink intensity (CSI) of Pinus densata in Shangri-La and analyze the combined effects of multi-climatic factors on CSI. We found that (1) GA can effectively improve the estimation accuracy of RF, the R[2] can be improved by up to 34.8%, and the optimal GA-RF model R[2] is 0.83. (2) The CSI of Pinus densata in Shangri-La was 0.45-0.72 t C·hm[- 2] from 1987 to 2017. (3) Precipitation has the most significant effect on CSI. The combined weak drive of precipitation, temperature, and surface solar radiation on CSI was the most dominant drive for Pinus densata CSI. These results indicate that dynamic models can be used for large-scale long-term estimation of carbon sink in highland forest, providing a feasible method. Clarifying the driving mechanism will provide a scientific basis for forest resource management.

Risk-based bridge life cycle cost and environmental impact assessment considering climate change effects.

Scientific reports, 15(1):725.

To enhance sustainability and resilience against climate change in infrastructure, a quantitative evaluation of both environmental impact and cost is important within a life cycle framework. Climate change effects can lead performance deterioration in bridge components during their operational phase, highlighting the necessity for a risk-based evaluation process aligned with maintenance strategies. This study employs a two-phase life cycle assessments (LCA) framework. First, risk assessments are conducted to evaluate the impact of climate change on steel plate girder bridges and prestressed concrete (PSC) girder bridges under identical structural conditions. The reduction in flexural strength of steel plate girders and PSC girders due to changes in environmental variables such as temperature and relative humidity, induced by various climate change scenarios, was evaluated analytically. Subsequently, life cycle environmental impact and cost assessments were performed, including maintenance outcomes derived from risk assessments. The findings revealed that the environmental impact and cost could increase by approximately 12.4% when climate change is considered, compared to scenarios where it is not taken into account. Sensitivity analyses were performed to identify the key factors influencing environmental impact and cost. The analysis determined that the frequency of preventive maintenance, the recycling rate, and environmental cost coefficient weight in the life cycle assessment significantly affected the results.

Transition from multi-year La Niña to strong El Niño rare but increased under global warming.

Science bulletin pii:S2095-9273(24)00941-1 [Epub ahead of print].

El Niño-Southern Oscillation (ENSO) exhibits a strong asymmetry between warm El Niño and cold La Niña in amplitude and temporal evolution. An El Niño often leads to a heat discharge in the equatorial Pacific conducive to its rapid termination and transition to a La Niña, whereas a La Niña persists and recharges the equatorial Pacific for consecutive years preconditioning development of a subsequent El Niño, as occurred in 2020-2023. Whether the multiyear-long heat recharge increases the likelihood of a transition to a strong El Niño remains unknown. Here, we show that such a transition is rare but more likely under transient greenhouse warming. In boreal spring and early summer after a multiyear La Niña, despite a substantial recharge in the western Pacific, thermocline remains anomalously shallow and sea surface temperature (SST) remains anomalously cold in the equatorial central Pacific. The cold conditions inhibit an ensuing eastward movement of atmosphere deep convection out of the warm western Pacific, delaying onset of ocean-atmosphere coupling, and hence growth of an El Niño. Under a high emission scenario, such a transition is still rare but more than twice as likely. The projected change is consistent with a projected weakening in climatological zonal SST gradient that promotes the eastward movement of atmosphere convection and a projected intensification in upper-ocean stratification of the equatorial Pacific that enhances the ocean-atmosphere coupling. Our result provides predictive insight of El Niño after multiyear La Niña, and advances our understanding of ENSO transition under greenhouse warming.

Cities worldwide have established plans and policies to achieve climate-neutral and climate-resilient objectives in recent decades. Researches have demonstrated that Climate Change Action Plans generally fail to include mitigation and adaptation approaches in their planning processes, despite their importance. A proposed multilevel assessment of Climate Change Action Plans, urban regeneration, and building projects was used to analyze the ten cities most sustainable in terms of developing environmental strategies, including local climate action to determine the degree of adaptation and mitigation integration in cutting-edge contexts and to identify measures that show synergies and co-benefits for urban design practices. Climate Change Action Plans, urban regeneration and building projects have been evaluated through scoring methods to determine firstly the level of integration among adaptation and mitigation and secondly the most used urban design solutions that addresses both approaches. Almost all of Climate Change Action Plans have "moderate" and "early" integration, with the most advanced in North American cities including Toronto, Montreal, New York, and San Francisco. Climate Change Action Plans partly influence urban regeneration projects. Among the cities studied, Royal Seaport and Hammarby Sjöstad in Stockholm stand out as the most advanced in terms of including measures for both mitigating and adapting to climate change, as well as the extent of activities carried out. North American building projects have the highest adaptation and mitigation strategies. Climate Change Action Plans, urban regeneration initiatives, and building projects analyzed have displayed measures to include both climate change mitigation and climate change adaptation benefits into urban design.

Prioritization of climate change mitigation strategies for coastal regions using the Analytic Hierarchy Process.

Marine pollution bulletin, 212:117516 pii:S0025-326X(24)01493-0 [Epub ahead of print].

This study utilizes the Analytic Hierarchy Process (AHP) to prioritize climate change mitigation strategies for coastal regions systematically. The AHP, a robust data-driven decision-making framework, was employed to evaluate five strategies: Mangrove Restoration, Zoning and Building Codes, Seawalls, Coral Reef Protection, and Relocation Programs. The analysis revealed that Mangrove Restoration emerged as the most effective strategy, achieving the highest score of 0.65 due to its significant environmental impact and long-term sustainability. Zoning and Building Codes followed closely with a score of 0.58, showcasing their cost-effectiveness and regulatory advantages. While effective in urban areas, Seawalls ranked third with a score of 0.48, indicating limitations in social acceptance. Coral Reef Protection and Relocation Programs scored 0.46 and 0.38, respectively, reflecting their higher costs and resource intensity. The findings underscored the importance of prioritizing strategies that balance ecological health and socio-economic feasibility, offering actionable recommendations for policymakers and stakeholders. This research identifies key challenges such as balancing ecological health, socio-economic feasibility, and resource limitations. Our framework addresses these by integrating multi-criteria evaluation, presenting novel prioritization insights for climate adaptation strategies in coastal regions.

Current food trade helps mitigate future climate change impacts in lower-income nations.

PloS one, 20(1):e0314722.

The risk of national food supply disruptions is linked to both domestic production and food imports. But assessments of climate change risks for food systems typically focus on the impacts on domestic production, ignoring climate impacts in supplying regions. Here, we use global crop modeling data in combination with current trade flows to evaluate potential climate change impacts on national food supply, comparing impacts on domestic production alone (domestic production impacts) to impacts considering how climate change impacts production in all source regions (consumption impact). Under 2°C additional global mean warming over present day, our analysis highlights that climate impacts on national supply are aggravated for 53% high income and 56% upper medium income countries and mitigated for 60% low- and 71% low-medium income countries under consumption-based impacts compared to domestic impacts alone. We find that many countries are reliant on a few mega-exporters who mediate these climate impacts. Managing the risk of climate change for national food security requires a global perspective, considering not only how national production is affected, but also how climate change affects trading partners.

Empirical studies on the impact of climate change on mental health in PINs were evaluated by using the Quality Assessment Tool for Studies with Diverse Designs (QATSDD).

RESULTS: Six studies from the Solomon Islands, Cook Islands, and Tuvalu were identified, indicating significant mental health impacts from sea level rise (SLR) and extreme weather events with compounding and mitigating effects across diverse groups. The Skills for Life Adjustment and Resilience (SOLAR) program was highlighted as a promising culturally adapted intervention.

CONCLUSION: Climate change significantly impacts mental health, particularly in PIN communities facing SLR and Extreme Weather Events (EWE). Culturally sensitive interventions, local knowledge, and further research are vital to mitigate these effects and support well-being.

Worry related to climate change in Brazilian adults.

Trends in psychiatry and psychotherapy [Epub ahead of print].

INTRODUCTION: Climate change is happening, and feeling anxiety can be seen as a natural response to it. Climate anxiety is the worry about the climate crisis and could be related to specific emotions and thoughts. The aim of this study was to assess the prevalence of worry about climate change, and to describe the emotions and thoughts associated to it in Brazilian adults.

METHOD: Cross-sectional study with participants aged between 18-42 years (n=323). Data were collected online using the questionnaire developed by Hickman and colleagues, which assesses the worry, thoughts and feelings about climate change.

RESULTS: 88.5% were worried about climate change. The feelings of sadness, powerlessness, fear and anxiety were reported more often among those who were worried. The most frequent thoughts were: "People have failed to take care of the planet", "The future is frightening", "My family's security will be threatened" and "Humanity is doomed".

DISCUSSION: In this sample, the majority of the individuals were concerned about climate change, and they showed more negative emotions and thoughts when compared to individuals that were not concerned. Future studies should take care to not understand natural worries and anxiety responses to climate change as pathological.

Impact of climate change, biodiversity loss, and pollution on the incidence and manifestation of depressive and anxiety disorders.

Current opinion in psychiatry, 38(1):35-40.

PURPOSE OF REVIEW: Climate change, biodiversity loss, and pollution present a major threat to health. Although emphasis has been put on physical health impacts, evidence on the mental health consequences is now also accumulating quickly. Given the rapid developments in the field, this article provides an expert opinion on the emerging research.

RECENT FINDINGS: Umbrella reviews are adding more high-level evidence on the associations of environmental crises and mental health. Individual studies are focusing on specific aspects of environmental crises and mental health, shedding light on potential direct links between climate change and mental health. Further studies are aiming to quantify individual burden and societal cost of the environmental crises and mental health nexus and to identify those most at risk for negative mental health outcomes. Many studies focus on eco-emotions, attempting to characterize them further, provide tools for quantification, and to determine their effect on functioning.

SUMMARY: Although the accumulating research on the impacts of environmental change on depression and anxiety is filling important knowledge gaps, important questions remain, for example concerning the risk factors for the development of mental health disorders caused by ecological crises, tailored preventive strategies, and concerning the effects of biodiversity loss on mental health. Health systems need to further develop responses to these environmental crises.

A copula-based multivariate flood frequency analysis under climate change effects.

Scientific reports, 15(1):146.

Floods are among the most severe natural hazards, causing substantial damage and affecting millions of lives. These events are inherently multi-dimensional, requiring analysis across multiple factors. Traditional research often uses a bivariate framework relying on historical data, but climate change is expected to influence flood frequency analysis and flood system design in the future. This study assesses the projected changes in flood characteristics based on eight downscaled and bias-corrected General Circulation Models (GCMs) that participated in the Coupled Model Intercomparison Project Phase 6. The analysis considers two emission scenarios, including SSP2-4.5 and SSP5-8.5 for far-future (2070-2100), mid-term future (2040-2070), and historical (1982-2012) periods. Downscaled GCM outputs are utilized as predictors of the machine learning model to simulate daily streamflow. Then, a trivariate copula-based framework assesses flood events in terms of duration, volume, and flood peak in the Kan River basin, Iran. These analyses are carried out using the hierarchical Archimedean copula in three structures, and their accuracy in estimating the flood frequencies is ultimately compared. The results show that a heterogeneous asymmetric copula offers more flexibility to capture varying degrees of asymmetry across different parts of the distribution, leading to more accurate modeling results compared to homogeneous asymmetric and symmetric copulas. Also it has been found that climate change can influence the trivariate joint return periods, particularly in the far future. In other words, flood frequency may increase by approximately 50% in some cases in the far future compared to the mid-term future and historical period. This demonstrates that flood characteristics are expected to show nonstationary behavior in the future as a result of climate change. The results provide insightful information for managing and accessing flood risk in a dynamic environment.

ESP Quick Facts

ESP Origins

In the early 1990's, Robert Robbins was a faculty member at Johns Hopkins, where he directed the informatics core of GDB — the human gene-mapping database of the international human genome project. To share papers with colleagues around the world, he set up a small paper-sharing section on his personal web page. This small project evolved into The Electronic Scholarly Publishing Project.

ESP Support

In 1995, Robbins became the VP/IT of the Fred Hutchinson Cancer Research Center in Seattle, WA. Soon after arriving in Seattle, Robbins secured funding, through the ELSI component of the US Human Genome Project, to create the original ESP.ORG web site, with the formal goal of providing free, world-wide access to the literature of classical genetics.

ESP Rationale

Although the methods of molecular biology can seem almost magical to the uninitiated, the original techniques of classical genetics are readily appreciated by one and all: cross individuals that differ in some inherited trait, collect all of the progeny, score their attributes, and propose mechanisms to explain the patterns of inheritance observed.

ESP Goal

In reading the early works of classical genetics, one is drawn, almost inexorably, into ever more complex models, until molecular explanations begin to seem both necessary and natural. At that point, the tools for understanding genome research are at hand. Assisting readers reach this point was the original goal of The Electronic Scholarly Publishing Project.

ESP Usage

Usage of the site grew rapidly and has remained high. Faculty began to use the site for their assigned readings. Other on-line publishers, ranging from The New York Times to Nature referenced ESP materials in their own publications. Nobel laureates (e.g., Joshua Lederberg) regularly used the site and even wrote to suggest changes and improvements.

ESP Content

When the site began, no journals were making their early content available in digital format. As a result, ESP was obliged to digitize classic literature before it could be made available. For many important papers — such as Mendel's original paper or the first genetic map — ESP had to produce entirely new typeset versions of the works, if they were to be available in a high-quality format.

ESP Help

Early support from the DOE component of the Human Genome Project was critically important for getting the ESP project on a firm foundation. Since that funding ended (nearly 20 years ago), the project has been operated as a purely volunteer effort. Anyone wishing to assist in these efforts should send an email to Robbins.

ESP Plans

With the development of methods for adding typeset side notes to PDF files, the ESP project now plans to add annotated versions of some classical papers to its holdings. We also plan to add new reference and pedagogical material. We have already started providing regularly updated, comprehensive bibliographies to the ESP.ORG site.

Papers in Classical Genetics

The ESP began as an effort to share a handful of key papers from the early days of classical genetics. Now the collection has grown to include hundreds of papers, in full-text format.

Digital Books

Along with papers on classical genetics, ESP offers a collection of full-text digital books, including many works by Darwin and even a collection of poetry — Chicago Poems by Carl Sandburg.

Timelines

ESP now offers a large collection of user-selected side-by-side timelines (e.g., all science vs. all other categories, or arts and culture vs. world history), designed to provide a comparative context for appreciating world events.

Biographies

Biographical information about many key scientists (e.g., Walter Sutton).

Selected Bibliographies

Bibliographies on several topics of potential interest to the ESP community are automatically maintained and generated on the ESP site.
